can't afford a cooper/anschutz/walther/feinwerkbau...
First of all, good shooting - keep up the good work! I'm not much of an expert at all in this are, but I'd pitch in a couple of possible suggestions:
1. First, re-ask your question here:
www.rimfirecentral.com or one of the other rimfire-specific forums.
2. CDNN has some nice deals on Anchutzes sometimes.
http://www.cdnninvestments.com/dowournewcat.html . But they don't all have the adjustable stock you're looking for. However, you could get one then add the stock you want afterwards.
3. Similarly, if you're looking mainly for a better barrel and stock, then can you just get a different stock and barrel for your current action, much cheaper than a new rifle? Does anyone make these aftermarket parts for your 2000? If so, you'll likely need a good gunsmith to mate the barrel. The stock is something you can swap out yourself in all likelihood. Check here to start with:

4. If # 3 fails, then for an economy shooter, I'd look at a CZ452 or a Sako Finnfire (not AS economy as the CZ). Probably the Sako since it would be more likely to have the aftermarket parts you need, since Europeans are nuts about their rimfire matches. Yes, CZ is made in Europe too, but I wouldn't think they'd have the same level of aftermarket stuff (stocks, etc.) as the Sako. Also, you might check gun shows and pawn shops for old Winchester 52s - those things are shooters, as are some old Remingtons, and some come with nice target sights - BUT probably not with the stock type you're wanting.
5. EAA used to import some nice quality economy Izhmash target rifles from Russia with the target stocks, sights, the whole 9 yards, but their new importer (Rem) doesn't choose to import all of them. You might call remington and ask them. EAA still imports the Ishmash airguns, but no firearms - I believe Rem has the rights to those. Man, I may start to dislike Remington if they prevent the importation of some of the excellent Izhmash guns. They are currently importing & selling some other rifles & shotguns under their "Spartan" line which EAA used to import, but these are Baikals, not Ishmashs.
