One year on from my first post in this thread and I've gone from three up to six. In that time I've also sold two and got one more for sale. If that sells it'll fund a Jazz that I've got one eye on in the classifieds.
I don't want to gig and I don't in all honesty want to play every day. They are nice things to own though and, as has already been stated earlier in the thread, are quite benign in the great scheme of collecting things. They hold their value and, if you choose wisely, don't depreciate (but I'm not doing very well in respect of the one I'm selling now).
They'll all go up for sale eventually, when I need the money for something else!
