I collect them also. I have so far a strummol8 giulia, love, stb 2.5, about 4 of each yyf elec-trick and short circuits, a trompos space roller graffiti, a micro top hollow and solid, a microtop hollow copper, a BK, a Mozu spin koma, I just ordered that bearing koma also. I don't have a spintastics yet so I want to get a couple. Yeah I gave only been into tops for about a month but the bug bit me hard. There is just something about them. Like rotating art.
