Tommie, it's common knowledge among shooters who have been using prefit/drop in barrels. They can be had for less than $200 to $515. With that range of price spread there has to be a range of quality. As far as I know, the only high end barrel maker offering a prefit is Krieger, selling for $515(correct Me if I'm wrong). There are some $350 barrels that are well made and winning matches. Even the $200 offerings are better shooters than almost any stock/factory barrel. There "are"some Savage Factory rifle shooters winning matches.
In general,the seller can't get as much money for a prefit, no matter the quality of the barrel blank. There are several reasons for this. How many chambers were cut with the reamer that chambered Your barrel?The tendon threads were cut to a stock dimension, not matched to Your action. It likely won't be from a top quality barrel blank. This being said, there are many prefits out there that shoot very well.
If You are interested in competive match winning accuracy, You should purchase the top quality blank of Your choice($350/$400?),send it and Your action to the top rated Smith of Your choice($350/$400?), and have him do the work. And while Your at it, You should have Your own reamer, You will need it again sooner than You think.
This is My opinion, based on My experience with prefits, despite My limited knowledge of precision shooting.

Good Luck
