What caliber? Can you get the twist and contour you want?
Not sure what "a good price" is but it may make a good shooter for you.
What is the application? Hunting? Hard for anyone to say what to expect as it's not as commonly used for custom builds ie bolt rifles as other brands. They do supply a lot to industry so their specs can't be too bad.
It's a cost-benefit/value decision IMO.
This nails it.
A couple of other things to think about. The Cooper barrels made by Wilson for Cooper are machine-lapped, not hand-lapped, to me it makes no difference since I have faith in a good job from a properly set-up machine.
Putting a Cooper barrel on will not necessarily make a rifle that shoots as well as Cooper's do. There are other things in that equation - such as tight tolerances, receivers that are true, good chambering, hand-bedding, etc. You may well spend the money on the barrel, along with fitting and chambering and end up with a rifle that shoots no better than any other off the shelf rifle.
Like most other things in life - you pay your money and take your chances.
