We used Under Budget Kitchens in our old house. I thought they did a nice job. I think the name "Under Budget" is kind of a misnomer, though. We didn't overpay with them, but they weren't really cheaper than anyone else's quote.
For countertops, DO NOT use Dela Tile. They were awful. The final result was fine, but the process of picking the slab and any communication was terrible. We went with them because they were cheap. Bad decision. They do backsplashes, too. Wouldn't go with them.
