I just went through this...
I just went through a similar search and settled on an '85 Tall Rig, very well equipped, and in excellent condition. You will find prices similar for certain model years, look out for any apparent bargain, there may be problems. If you find a boat you are interested in, proceed with a survey from a certified marine surveyor whose references you've checked. Significant problems could be serious blistering, engine problems, deck hull separation. Replacing standing rigging, running rigging, can be relativly minor expense and negotiated in an offer. Consider what you want, my boat has refrigeration, AC, autohelm 4000, AM/FM/CD, custom cockpit cushions, bimini, new sail cover and pedestal and winch covers etc., etc. The latter stuff really adds up but may not add much value to the boat per se, so look for a boat that has stuff on it, you'll likely find one. This is a great sailing boat, you won't regret it! Good luck!
