I have a Yugo AK Underfolder (M-70)
You can still get Romanian AK's pretty cheap but the furniture isn't the best on those so you might want to change to at the least refinish it. The WASR's have a milled receiver and a lot of the AK snobs don't like them but they work very well. SuckLead has one if I remember. I'm sure she can say how well or not they work. I did have one and really want another one.
If you can find a good SKS they are not too bad either. I have a D Type Chinese that I put a Tapco stock on that I live to shoot. I had redone the original stock but thought I'd update it . I like the D Types because they use AK mags so you are not bogged with the box mag many have or the high cap SKS mags. I like being able to use the same mags with my AK and my SKS.
Since this pic was taken I have changed the scope out to a holo site that I got in another trade.
There are all kinds of different rifles that are not too pricey. I thought I'd show you two I have. he SKS I got for 300.00. A little high for an SKS maybe but after seeing what they sell for ion other places I come in pretty cheap.
There are the double Star AR's too. Most of the models they make are a little cheaper than some of the high end models but they are really nice rifles. The people that started Double Star worked for some of the big guys in the AR market. They went to making their own I can't remember exactly when. It seems they got in just before the 1st ban. Many people building their own AR will start with a DS receiver. I have a Star-15 Rifle. It's nothing fancy but it's more accurate than I thought it would be. And was a lot cheaper than many others. Here it is.
There are many others but I thought this might help you a little and I do love showing them off anyway
