Well, the Fajen Sporter or Silhouette are gonna run you around 100 Bucks. Unfinished. The finished ones are around 150 Bucks. Same as the Bell & Carlson in synthetic. I guess it's up to personal preference, but I'd get the Fajen Sporter and finish it myself. Saves you 50 Bucks, plus you get to take pride in having done something that everybody at the range is gonna drool over. Right!?
If you wanna go real cheap, Choate makes that Dragunov Style synthetic stock and they sell it for 65 Bucks on their website. http://www.riflestock.com/ Sure, it's not a thumbhole, but 65 Bucks!?
