I've bought quite a few guitars and maps the last few years; some on eBay and some at local stores or Craigs List. Can't seem to get enough equipment and I'm running out of room to store the stuff, but compared to some guys, the collection is small.
Then there's the time spent reading magazines, blogs, books and websites dedicated to guitars and amplifiers.
If I was independently wealthy we would have to add on to the house; of course we would probably be in a bigger house.
