336 Vs. 337?

Thanks to all for the valuable insight, I looked at the ad for the 77 337, it seems like the good price is because the plane has 8000+ hrs on the airframe. So another question has arised, is this something really to consider? I have always thought that I would not like an airplane with more than 5k or so on the airframe, but I am not sure if this is a good way of thinking. Would this be a problem?
