Comparing Searunner 34 and 37

[Jerbob]

I'm considering buying a searunner. I think a 34 would be about the right size, but I notice there are a lot more 37's for sale. A friend who turned me on to Trimarans, especially searunners, said that there are a lot of advantages to the 37's which is why they're so popular. My future income while retired will be limited so I wondering how much more others see upkeep would be for a 37 compared to a 34. I'm not lookig for exact figures, but rather just people's experiences or what they've seen or heard from others related to this issue.
