Have you thought about painting them? It's an option. I recently painted my "honey oak" kitchen cabinets. It was rather easy and not too timely, as I too was on a budget.
Im so super pleased with the outcome. I spent about $50 for a completely new look. Brought our kitchen into the current century.
Here are simple instrucitons:
Remove all hardware, removed doors, rough sand everything, wipe with dry cloth. Choose a high gloss good quality paint ( I got Behr @ lowes). Apply 1st coat of paint cabinets, apply 1st coat to doors, let dry completely. Apply second coat of paint to cabinets and doors. Make sure all paint is completely dry, attach hardware, rehang doors.
