Not sure what you consider and arm and a leg, but I've had luck buying from <A HREF="http://www.bhphotovideo.com" target="_new">http://www.bhphotovideo.com</A> and <A HREF="http://www.adorama.com" target="_new">http://www.adorama.com</A>
I bought my Canon EOS Kiss Rebel 300D,Sigma lens,& 1GB CF card from B&H. They have a good website with lots of detailed product info. I highly reccommend them.
I'd recommend going to <A HREF="http://www.bhphotovideo.com" target="_new">http://www.bhphotovideo.com</A>
as well. It's customer service is excellent and it ships fast.
