i'm looking for the best bang for my $$ on countertops

For the DIYer you get a lot of bang from granite and concrete countertops.
I've seen 3/4" granite slabs with prefabricated bullnose as low as $5/sf.
Concrete is gorgeous when its done right but need more maintenance - you see
this at very high end custom kitchens. Both are so cheap is you have some
skills and a friend or two to provide the muscles.
