I too am out of room. Tapped out at 11 in the basement. Trying to convince my wife that we should convert my son's old room (with his blessing) to an exercise room freeing up space for my pins in the basement. It'll take a little time, but I think it will work.
9 in there now, looking to sell one, leaving 8. Got F14, CC and MB coming, which would max out the space there.
Now I am close to a deal of a very nice PM and an RFM, both for $2600. Cannot turn this down when it happens. Nice problem to have.
Quoted from markmon:
Totally understand. I built a storage shed / shop in the backyard to rotate pins in and out. I can store 10 out there and work on them there then cart them in. It wasn't too expensive. You might consider something similar.
I know a guy who built a two story building with an elevator. Top floor a gazillion pins; bottom floor a workshop and paint booth.
