I don't know if I even truly consider myself a "collector", but I greatly admire those who do! I seem to grow fondness for machines that I have seen and incidently gained knowledge about. Often times from posts on forums like this one! Someone will share their really cool machine...and then all of a sudden I see one at a sale...and because I know just the slightest thing about it, it must come home. I try to avoid at this point anything too big unless I LOVE IT because my home is small. I avoid anything I have more than two of...although I'm thinking of getting a thired 15-90 so that all three of my kids will have one. I gravitate towards people powered machines versus electric because...well...electric can be a pain in the you know what.
