If you are interested in building more than the outcome then I would say go for it. I wont guess on prices though because I don't know situation at states, you'll save some money comparing a brand new one but you'll spend lot of time on your project. For me the journey was quite relaxing (mostly) and totally different than my day job.

Bottom line is that if you are just building to get a boat to sail you better get yourself brand new or used boat instead and go sailing <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />.
