As the wife of an electrician, I can tell you that used cabinets are not all that hard to find. And there are certain "seasons" if you will, when they are very plentiful. People usually start to remodel around tax return time, continuing through the summer, then it hits "high" season in very early autumn, around September/early October (in order to be finished for the holidays and the children out of the way and back in school).
Sources:
1. Watch your newspaper want ads. The deal I found last year was SOLID walnut cabinets, 18 linear feet of them, uppers and lowers for $450! (The lady decided she wanted a lighter look in the kitchen).
2. Call all the local remodelling contractors and let them know you're looking. Sadly cabinets are usually just ripped out and thrown away; however if the contractor has a buyer for them, they'll remove them carefully. You may or may not be able to negotiate being on-site with them -- depends on their insurance clauses. (And don't overlook talking to the cabinet people at places like Home Depot and Lowe's. They do a huge volume in kitchen remodelling.)
3. Consider placing an ad in the paper notifiying homeowners that you're looking.
4. The European look makes for wonderful photos; however you might consider doing what the Swedish and Italians do -- hang sheered curtains, especially on your lower cabinets to keep out the dust/dirt. Just a thought.
Don't overlook, especially on your upper cabinets using old windows as door fronts. Can be very attractive. Avoid these on lower cabinets unless you've got tempered glass.
Happy remodeling.
