I'm considering a quick spruce up on my Boston condo before selling, and am thinking of replacing my cabinets. I may have found a great deal on some used cabinets.

Can anyone tell me:

1-Are there specific issues I should watch out for with used cabinets?
2-What might be the approx cost of installing a straight 112 inch run (upper and lower) of cabinets (1 sink cut, 1 dishwasher cut, that's it)
