S2
We just made the move up ourselves. S2 builds a nice boat and I am comfortable in it at 6 feet even. I have posted much about it on the s2owners.com sister site. 6'2" might be tough for most 30 footers. You might want to go as high as 32-34 feet if you are looking for head room. Given my Wife's limited desire to sail I figured that overnights would be few and far between, as usual, so interior accommodations were less important than other considerations.
My advice, after going through it myself this year, is to look at a bunch of boats to get an idea of likes and dislikes then make a list of need to haves vs. nice to haves. Once we took this approach we settled on a tee-shaped cockpit with wheel steering (much better for a rotation issue I have with my back...no pain since and I couldn't man a tiller for three hours) as our main need everything pretty much fell into place. This need eliminated most of the boats in our age / price range and I identified the S2 9.2A as a boat I was interested in. We looked at one and after that it really was just finding one. Keying in on just one boat meant that we didn't get a great deal, as we essentially ended up buying the best one of a handful in the area, but no regrets as we plan to keep her for a while.
Based on weight, the Lancer 30 is a pretty small 30 footer. It is about 8200 lbs, and my 9.2a is over 10,000 as are the O'day 30/31 (the 302 is about 8000) and the Catalina 30. Weight is a good measure of relative size between boats of equivalent length, but not always. The Newport 30 is a pretty big boat inside, but is light at about 8000 lbs, but it is pretty lightly built too in my opinion and I looked at a few and had a survey done on one.
Every boat is a compromise. You just need to decide where you are / are not willing to compromise.
