How's the search going? I looked for a 3100 Open for months, ended up finding a 2900 Open that I fell in love with, and 5 seasons later loving it more and more. Sounds like you have a good idea of what to look for. I'd also look for wetness/rot inside the swim platform and in the opening hatches on the cockpit sole. I haven't had any issues with that but I know some have. Another one to look for is the seals all around the windshield. The gaskets and the silicone get old and the windows start leaking. It'd a big job to take them all off and re bed all the glass, I'm currently paying 2k for that job and I'd budget that regardless if it hasn't been done yet (and I'm also having my windshield covers powder coated while I'm at it). Obviously look at the stringers. Also make sure if saltwater that you have new risers or budget for them, and look for corrosion on the engine mounts, alternators, etc.

Good luck!
