Scott, it's "6 of one..."
Both are similar production boats, similar quality, etc. Some might say the Catalina is the way to go, as they're still in business, but, really, how much do you reaaly need that must be purchased from the builder, and what are the odds they still carry it?
Look at the condition of each boat, and compare the extras (spare sails, smaller jibs, depth finders, VHF, etc.). Given two similar quality boats, I'd buy the better value, whether that's a lower price, or more bang for the buck, as those options can get pricey fast. If there's a big quality difference, go with the better boat. For a newbie, you'll save time and money in the long run.
