I found one at a pawn shop and they were asking $150 for it. I told the owner that was a little steep and he said he would sell it for $120. Possibly.

There's one on eBay and the current bid is $100 plus $30 for shipping.

I'd really like to find a "broken" one at one of my favorite saw shops. Over $100 seems too much for a used weed trimmer.

Is there really that much difference between the 21, 23, and 25cc motors weight and power wise? Keith mentioned that the only difference between the 21 and 23.6cc motors is the piston/cylinder. My 21cc has 2 head bolts and 3 pullstarter bolts. Pics I've seen of the 23cc motor show 4 head bolts and 4 case bolts. If not, I could just order the piston/rings/cylinder and put in on my other 21cc block/crank.
