Ok man-find out if the SLR-105 A1 is actually available; the website shows it as available, but make sure you talk to someone. The SLR-105s have been discontinued, maybe for good, so if you can find one you should jump on it. They are the closest thing to a real AK-74 type rifle that you will ever find.
Arsenal makes questionably the best AK type rifles available. They're superior in nearly everyway to the Century WASRs. If it were me, I would sell that WASR in a heartbeat to get an SLR-105, I mean I wouldn't even think about it. The SLR-105s are certain to increase in value, too.
Only two possible downsides to the 105s: crappy black paint for a finish and the availability of 5.45 ammo. The black finish will come off in spots, often within a few trips to the range. Spill some Hoppes on it, and there goes the paint. Eventually you may want to put on a better finish, either do it yourself or have it done professionally. As for ammo, 5.45 is VERY scarce right now. Be prepared to search and/or wait for some. Many seem to think the ammo situation will improve, but only time will tell. The 5.45 round itself is a joy to shoot, and IMHO superior to the 7.62x39 cartridge. Extremely low recoil and much, much more accurate.
Anyway, let us know what you decide to do.
