What about a Nikon D60?
Might as well save a little and go for a D40 or D40x imo.
I'd avoid a 350D, that is also very old and spending a little more can get you a lot better features. The Alpha 100 is more capable but I found the handling and layout pretty awful. The Olympus is likely to be a fine camera but sticking with the bigger brands gives you easier access to lenses.
A Canon 400D would be my budget-bet.
Question why you're getting a DSLR? I think you'll likely want to move on so quickly (you can buy compacts for the same money today which have better low light performance etc than those DSLRs) that it'll end up being wasted money. Better to save and buy something that'll last you a while.
dont say that i got one last week lol
How are you finding the 350d?
Over my budget unfortunatly. Even the D60 will be a stretch.
At the moment my budget is looking like.
Sony A100
Sony A200
Sony A300 (Maybe some have gone for just over £220 with a lens
Canon 350D
Olympus E-410
Olympus E-420
So hard choosing.
a230 for me, out of those
