Well....
Low cost and actual value may be miles apart.
In our old house, we had a gent come in and veneer our existing cabinets and install new doors and drawers. He also built a new cabinet for the other side of the kitchen. Truthfully, I wasn't real thrilled with a couple of the veneered places, but the overall job was fantastic. The work he did wasn't cheap, but it was quality. We also had new Corian countertops installed and I installed undercounter lights and a tile backsplash.
A neighbor had the same thing done by another company and hated it from the minute the sales weasel walked in the door to the time we moved out. The only thing she did like was the price...
I would 'interview' whomever you choose, should you go that route instead of doing it yourself. Get references and check them. Ask the references if that company or person did work for others not on the list.
Good luck.
