Seems like you're gravitating toward the "Soviet designed weapons" theme. Not a bad theme to start out with, since most of the weapons on there are affordable and plentiful.
Get a Makarov pistol next. That was the service sidearm of the Warsaw Pact (and all other Commie nations) for pretty much most of the Cold War. The Tokarev (I'm guessing your "norinco pistol" is a copy of the TT-33) was the USSR's pistol during WW2, but they phased them out in favor of the Makarov after the war. Makarovs, like most other Soviet-designed weapons, are robust, reliable, simple to operate, maintain and break down, and reasonably accurate.
You can also get a Mosin-Nagant carbine - either the M38 (no bayonet) or the M44 (side-folding bayonet) Those are affordable and fun to shoot as well.
The PSL is a Dragunov wannabe - it's not actually a Dragunov, but it does look pretty cool and it is an actual DM (designated marksman) rifle. It's not as accurate as a true Dragunov, but for about a 5th of the price of a real one, what would you expect? Operationally, the PSL is just a up-calibered AKM, chambered in 7.62x54 instead of the usual 7.62x39.
Good luck.
