I've had my Rebel XT since it came out and I use it in very dusty
conditions:

I've cleaned it twice in 2 years, the first time it had about 7 noticeable
spots, this time it had about 12.  Both times it only took a blower to clean
it.

What the hell is wrong with RichA's brain?

All the time.  During the long weekend when I took the shadow and cross
pictures I changed often between my 35mm f/2, 24-135mm, 10-22mm, and
100mm macro.

Yes, but the dry desert air is not home to the dust we see on sensors.

Try shooting outdoors in the spring when pollen fills the air, or
indoors where the carpet dust and lint is everywhere.

Oh, there was tons of pollen here last weekend:

I'd like to see a photo of the cloudless sky at f/32.

After that weekend was my second cleaning in the last 2 years.  13
spots.  Gone with a few puffs of air.

Perhaps I should explain:

When viewed in Photoshop after selecting "Auto Levels", all dust will
then become readily apparent.

Perhaps I should explain:

Dust is usually such a non-issue, even to those of us who change lenses
often and in less than pristine conditions, that we don't worry about it
until a persistant dust spot or two appears.  Then about 10 minutes with
a lifted mirror and blower bulb are all that are required to get it
clean again.

In the last 28 months I have cleaned the sensor twice.  Total effort
about 30 minutes.  I spend more time that that scanning and editing a
single film frame.

A blower usually does the trick. I also got a dime store makeup brush,
which can be static charged with canned air (a bulb blower doesn't quite
work so well) or simply used with a blower to shake off stubborn specks.
If you let things go for too long, humidity &/or smoke can glue the
grime on & that's where a wet cleaning with swabs & fluid is needed but
DON'T use a swab before blowing &/or brushing: I wasted a bunch of
expensive swabs that way just pushing dust back & forth & getting
frustrated camping in death valley when a blower would have probably
removed 99% of the dust. I work outdoors changing lenses in the dust all
summer & it's no big deal.

Once Canon or Nikon produce a working anti-dust system, i wonder how
many will turn it off so they can keep enjoying their 10 minute blower
interludes?

It realizes that your experience is not everyone's and dust as we've
seen from hundreds of examples on pbase, etc, IS a problem for
people.  The FACT they can sell anti-dust kits for upwards of $200
should TELL even the DULLEST person this is a FACT.

$200!?!  What a bunch of idiots.  Even if one does have a dust problem
one doesn't need to spend $200 for an effective anti-dust kit.

All that means it that there are plenty of gullible idiots listening to
people like you! Nothing more.

Sure, but can you post some stuff about photography first or we will have
nothing to read.

You're not kidding!  For less than $200 you can buy a NASC and use it for
various other household tasks like pushing beer or for refrigeration work.
Buying any other kit is totally and utterly foolish!

No; I'm from the world where they successfully marketed *pet rocks*;
getting people to buy something proves absolutely nothing at all,
beyond that you got people to buy the thing.

Well quite.  I see someone on eBay just sold a pen1s-shaped crisp (US:
potato chip).

Says it all really.

I went for a LONG time with my 10D with no dust problems...but later I
certainly ran into it.
I've had only minimal dust issues on my 5D....
Some folks rarely shoot stopped down, which can make it harder to see.

That will remain a mystery, I'm afraid...

So is it better to advise people (=novices) to be careful or is it better to
tell them there's no way dust can get into their SLRs?

And which of these are you doing?

It's better to advise them as he has done: it's no big deal, and even
if you do have to clean the sensor, it takes only a few minutes of
light work.

I can't understand why you'd even bother to ask the second part of
your question since it isn't something the OP, or anyone else, stated.

A RichA clone/puppet/alter ego would ask that.

RichA is not very amusing these days and is wearing mighty thin.

I guess. Meaningless or out-of-context questions can get old after a
bit. And RichA has been around, here and elsewhere, quite a bit.

I don't use sock puppets, unlike some of the kooks here.
