I have a red Craftsman 1.9 branded Poulan XX-D that's set up with 1/4" chain. Little bugger pulls it very well, and is a well balanced saw. I'm sorting out some oiler issues, and then I'll put a dime tip carving bar on it with some Oregon 25AP.
Also have a few 1/4" pitch sprockets for the XXV series saws, and will probably set up one of my XXV's (probably my Craftsman red 1.9A branded 25D) with 1/4". They'll be fun to do some carving with.
I could have gotten a partial roll of Oregon 25 (somewhere between 50 and 100' on an OLD 100' reel) for $50 at an estate sale a while back. Was already blowing all the cash I had on hand on other stuff (including a box full of carb diaphragms, a Husky 2100CD crankcase and starter, and approximately 46' of Oregon .404-.063 skip square chisel chain), and had to leave the 1/4" stuff on the shelf (along with a partial reel of .325 pitch chain and a NICE Echo CS302S). I went back later with more green, and all the stuff I'd left behind was gone....
