I nearly purchased a helms 27 a year ago, and tried to research them without much success. What I did learn, however, is that the maker, Helms, wanted to make a "better Catalina." In my opinion, he didn't succeed, but I think they are well regarded for what they are. The H27 I saw was going for $12,000, and was in great shape. Minor osmosis, new sails, new running and standing rigging. Having recently purchased a boat (which I love), I'd definitely have it surveyed by someone who knows what they're doing, and who has no conflicts of interest. One thing I've learned over the past year is that some boats are actually worth less than $0. What I mean is that over time you'll see that it's a screwed up mess, and that you want something else. The problem: You won't be able to get rid of it because no one wants to buy it. Just have it surveyed, even if it costs you a third of what the boat costs.
