Esox,
HS Precision seems to have a decent product, check out their web site. They also build custom guns that are guaranteed to under .5" under 30 cal.

I kind of went though a phase like you're in where I was going to glass bed and restock ... etc. I did a gun with the Accuglass bedding system on my own and basically came to the conclusion that the results really didn't justify the effort. Don't read this wrong, it was a good experience, but personally I'll agree with Jack. If it shoots within your acceptible needs, I wouldn't mess with it.
From what I gathered you'd be looking a post maket stock of approx $250 to $380 HS or McMillan these both have Aluminum bedding blocks and are nice and rigid. Even these, which are basically drop in style stocks for 700 Rems, can use glass bedding.
In fact if I were to spend the extra $ for a stock I'd probably spend another $125 - $150 to have it professionally bedded.
