snip about buying a Dslr.

Dont worry about the std. lens. It is good enough for most uses. there
is a review here:

So long as you dont use it at its limits, and close the aperture down
one or two stops, then it'll be fine.

I'm not sure you'll need a spare battery soon, mine has done around 400
shots now,and has not needed charging yet, and yes the charger does come
with it, though you will need to buy a memory card - 1gb is around £20.

No need to buy that stuff yet. the remote for the Canons is a small IR
switch, 2nd hand at around £10. If you do get a tripod, dont get a cheap
one, save for a better one that will actually keep the camera still.

good, and not so good pics.

If you must have a spare battery they are quite cheap from the likes
of 7dayshop.com - but you probably won't need one unless you plan on
being away from mains for a while.

The camera comes complete with charger. Again 7dayshop do a quite
cheap base unit (GBP7?) with an adapter extra (GBP2?) that will allow
you to charge the battery from 12V.

Memory cards are dirt cheap at the moment. 1Gb shouldn't cost you more
than GBP20 - get a Sandisk Extreme II, you don't need anything better
than that as the camera (350 anyway) can't use it.

A filter is a good buy as it protects the lens from fingers and
scratches. However unlike my Nikon 18-70 which takes a 67mm filter the
Canon is only 58mm which is a much more common size and therefore much
cheaper.

You won't need a flash unless you want to light a church or the like.
For most 'snaps' the built-in flash is more than adequate.

Remote? Forget it - you won't need it and its ridiculously overpriced.

Tripod? Well maybe, but down the road a bit.

A pouch case is a good idea. The Loewe range are quite competitively
priced - less than GBP30.

So you see it is not too expensive to get going. Get the camera with a
filter and then go and snap away. If you do find you need the extra
bits then think about it later, but for the moment just enjoy it.

You will probably need some software for picture correction and/or
editing. Picasa is free from Google and you will find that it offers
good presets that cover the majority of correction needs. If you find
you need more, get Adobe Elements 5 or PaintShopPro (in whatever
version is current) - there is no need to go to the (stupid) expense
of Photoshop.

Finally, to get the best from your camera shoot in RAW mode which is
an almost undoctored version of what the camera saw - jpg is corrected
quite substantially before saving. Then get yourself a good book on
how to use RAW and you will be amazed at what you can achieve.

Oh, and as I have a Nikon how do I know so much about Canon? My son
(who still lives at home) has one.
