I am hoping to have this same dilemma in a few months if we actually move - it's up in the air. I'm hopeful but only time will tell right now...
What I'm hoping to do is to find some kitchen cabinets that people give away on freecycle or craigslist and then put a piece of wood or a door or something on top if I can't get a piece of formica or something. I'm going to hit some second hand stores after - if - we move and see what there is to see. We have a fabulous Habitat store that sells donated building supplies and whatnot so I'm hoping to get something fabulous there :)
People give away old kitchen cabinets *fairly* often if you keep an eye on your local freecycle. and craigslist.
