It really depends on how much you want to spend and how accurate you want the rifle to be.
I would avoid the Rem 597. IMNSHO, it is a mostly plastic piece on shit. There was a gent who purchased one for use in our smallbore league and had nothing but problems with it. Also, since it was issued after 1994 you cannot buy standard capacity (>10) magazines for it.
10/22's can be made into a great rifle but out of the box they leave a bit to be desired, my opinion again. Most require a new trigger and should at least be shot with a gradual loosening of the barrel band to find the sweet spot with respect to harmonics.
I find it odd that so many people buy 10/22's with the intention of only keeping the receiver, adding all the aftermarket parts and then still singing the praises of 10/22's. I am not knocking those who do, it's your money spend it as you wish but after you strip the rifle of everything but the receiver is it still a 10/22? Why do I care?[:P]
There are companies that sell 10/22 receivers by themselves that you can build on but none come to mind at this time.
My suggestion:
You can buy the 10/22 If you have to have a semi-auto. Buy it and see how it works bone stock. More then likely you will want to replace the trigger, possible go to a bull barrel which will require a new stock.
Better yet, buy an older Winchester 52 or an Anschutz MP64 and shoot better than those custom 10/22'2 out of the box for close to the same money.[:D]
