joshp, i don't know about saving money, but it has saved my sanity for alot of years now. yea, someone said something about being a spiritual thing - yep! for most of us it is a lifelong hobby, no that's not the right word, committment, no that's not the right word.... passion, yea, that's it, passion. well anyway, there's lots of reasons, and when you find your reason, you'll probably never quit. when that happens, cost is of little concern.
