depending on the condition of the frame...you can find them from 200 at a gunshow to 250+ at a gunshop.
Barrels...factory barrels will fetch between 125-200 depending on length and caliber (some are rather rare/sought after whereas some are dogs...)
custom barrels like from Bullberry, SSK or Mike Sirois will fetch upwards of 400 dollars...more if they come with the custom dies and other specific items for that barrel/caliber.
I went through the typical "Contender-itis" a few years ago and now I have pared it down to a 17 HMR 20" and a 16.25" 45-70 with one rifle-stocked frame.
Two suggestions for calibers if you plan on getting into TC's....
If you reload...get a 30-30...30 WCF with a spitzer bullet can do amazing things on critters.
Second...a 44 mag....just because.
lol I know there are bigger and badder calibers out there...but the 44 mag is just kinda....mystical.
Also you will always have a good investment as these things hold their value rather well...just be sure to shop around...ESPECIALLY at gunshows...there you will find the best deals, generally.
Good luck!
