I have a Romy wasr 10. It's a fun, reliable AK and has actually surprised me accuracy-wise. I too laugh about back when everyone talked so bad about them and now suddenly they're widely considered a solid, serviceable AKM platform.
That said, I'd do a bit more research regarding the value of your BAR. I'm not very knowledgeable about them, but I have a feeling you could sell it on gunporker, pay cash money for the wasr and come out ahead with a few dollars in your pocket versus a 1 for 1 trade. It does sound like you aren't really using the BAR for much and the ak would be cheaper to feed so you'd like get more fun and use out of the ak.
