I have limited space that always seems to be full. Not as easy to sell a machine now as they are all machines that I want to hold onto whereas in the early days I was just buying anything reasonably priced that I thought may be a good machine.
Now though I look at machines that don't get played, especially when I have a few friends around. The ones that sit idle make their way to the top of the list of machines to sell when the time comes. There have been some machines on that list that I wish I didn't sell but at the time they didn't get played and were just taking up room and if they were still here today, it would be the same.
