If I were you I'd modify my own before I put money into a target model.
A target model around here costs about $350, a standard model costs about $160. With that $190 you can get a nice stock/barrel combo to go on you standard model, sell your factory stock and barrel for 20 bucks a piece and then you'd have $230 to spend instead of buying the Target model.
The hammer forged barrels are pretty though...
That's just my opinion.
If you want a non Target model then I don't think there's an accuracy difference between any of them. You can do the trigger work yourself if you've got the tinkering ability and confidence or put $30 into a Volquartsen hammer.
