Yeah, he does nice work. Not inexpensive though! Another easy is to send your 10/22 action to Clark Custom. He along with Volquartson were the early innovators in the super accurate bull barrel design for the 10/22. A fat barrel, Hogue overmolded stock, and a little trigger rework makes a nice little rifle.
John, be carefull, guns and shooting is another slippery slope just waiting to suck you in. The 5 shot one hole group is a similar challenge to a better track time, better ET etc. just not as expensive. Scratch that last remark, I've got (so far) approx $1500 bux in my .223 AR with more stuff on the build list......
