Well, if you can live with it as is, and you got them at a good price; then there's no reason to not grab one. Just bear in mind that even without modification there will be an issue with finding extra mags if you need them. And that if you put a scope on that top rail it will not hold zero. Otherwise, I'm sure it's a solid shooter and if that's all your looking for in a 7.62x39 rifle, I'm sure you'll be happy with it. A lot of people are, the folks that run into issues with them are the ones that want to change things and think it's as easy to do as a regular AK...
That said, how cheap did ya get them? Yep, even after knowing all the above, I'd still contemplate getting one because as I said, I have a thing about Zastava rifles...

twenty-five bucks for a single stack mag is a bit much.
Like I said, I'd pick one up if I could located one under $300; but at the usual price ($350) you're close to WASR-10 territory and I'd rather throw in the extra cash to get a rifle that is closer to a real AK.
