I wanted to try this, but our shoddy excuses for cabinets couldn't handle the weight, so I ended up with my first love, butcherblock.

Don't use the gardenweb search feature; it's practically useless. Use google and search for "gardenweb concrete countertops". Silverraven and frmrsdghtr did DIY concrete counters.

I love this kitchen make-over with DIY concrete counters from the Imperfectly Polished blog. Jessie posted links to her tutorial through the steps, too. You could ask her how they're holding up.

Thanks for the tip on searching- I found lots of great threads!

Concrete countertops can be very cool but it is not cheap and needs to be treated like marble. So unless you have a particular look you want, almost everything else is about the same price. You could DIY it ,however, if you are into that, but the end product would be uncertain. I looked into it seriously and decided to go with soapstone.
