If in fact the cabinet cases "Carcasses'"are square and solid sturdy, you could consider refinishing the face frames, and even totally new doors.
Be aware, there are many cabinet shops that farm out the actual doors .
Look for a small scale realistic price kitch cab door maker in your area, and check out the pricing for optional overall avenues.
Besides Google, call local small cab shops for referrals.
Unless you go the option of wash, scrub, sand and PAINT your doors, new doors may be more practical.
Re doing the wood look will be difficult, unless you go with somesorta antiqued look... again though... NOT a place to practice your first Rodeo.
Your old doors could be prepped and sprayed,end up totally Pro looking, but ONLY if you have done similar work before. Marc
