Hi Freebird and welcome to YF!
I can relate to your situation. Been there. I called it being "two-boat poor". It's not necessarily the cost, it's the time it takes away from doing the things that support your habit... like going to work!
The 58' is a great boat and makes a good live-aboard. We had one in the family for years and I lived on it many times, usually because my family was driving me nuts.
In the bang-for-the-buck category, a hard boat to beat. Of course, there is that dilemma of backing down a slip that you never had a problem with before.
