My agreement with DH is that I can have as many as I want but I have to keep them in MY room. I've got 8 machines; 2 of which are really just for looks as they don't run and I'm not skilled enough to make them run (they're not actually all that attractive; they just each look like the machines my 2 grandmothers used). I will NOT take on any more non-functional machines, and I keep telling myself I won't buy a machine if I won't actually use it.
I keep LOOKING at machines, there are so many awesome machines out there that are SO COOL (I want a Rocketeer so bad...and that recent thread on the Japanese ZZ machines had me drooling)...but I'm trying to keep my hands to myself. I don't know how to fix them, don't really have the space or inclination to really get into learning that at this point in my life, so I'm keeping myself restricted.
Of course, to my friends, 8 machines is absolutely ridiculous. OHH...if only they knew... LOL
