Depends what you mean by reasonalbe, there are none in the price range
of the D70 or DRebel. The Sigma 12-24mm (18mm with the focal length
factor on a D700) can be had for around $600.

Want to have some fun and not spend a zillion dollars. Lookup the net
for the Peleng 8mm ($200) and the Zenitar 16mm ($100). And you will
have to get a M42-to-EOS adapter to use these (I am assuming you have a
Canon dSLR). There are M42-to-Nikon adapters as well.

You can use the old FD lenses with the Canon digital SLRs. All you need
is a FD-to-EOS adapter and lots of patience. Check eBay, they are
available for around $90.

In full size (35mm equivalent) sensor cameras, there are currently only
three choices, the Kodak DCS Pro SLR/c (Canon lens mount) for $4500, the
Kodak DCS Pro SLR/n (Nikon mount) at $5000 and the Canon 1DS Mark II at
about $8000.  Not exactly "affordable" for the run of the mill photographer.
They are high resolution cameras, though, the Kodak offerings weigh in at
13.8 megapixels, the Canon at 16.7, more than twice the next best
"affordable" DSLR.
If you're looking for fixed focal length lenses, there doesn't seem to be
much available wider than 14mm, which won't give you the same field of view
as a 17mm on a 35mm film camera, unless you want to go the fisheye route.
Canon makes a 10-22mm f3.5-4.5 zoom that'll get you 16mm at the wide end on
a RebelD or 20D, Nikon makes a 12-24 f4, on their 1.5x sensor that will look
like a 18mm did on a 35mm film camera.  Olympus makes an 11-22 f2.8-3.5, but
their smaller sensor makes that something like a 22mm at the wide end.
KonicaMinolta and Pentax don't offer anything wider than 17mm, but, of
course.  Sigma makes a 12-24 f4-5-5.6 in several of the above mounts, but
the lens is rather slow.

The Tokina 12-24/4 lens is now available and I have a had time telling
the difference between that and the Nikkor 12-24/4 lens.  At $499 it's a
great buy for wide angles.
