Looking to buy a receiver (warning: newb & cheap)

[azzzz]

Hi guys

I would like some advice. I'm not much of an "home theater" person but I do want a receiver to "enhance" the sound of normal gaming and occasional movies. ATM, I am stuck to using the stock speaker that came with my Olevia 242 fhd (yes. I'm cheap) and it's actually worse than the speaker on my Hyundai 32in LCDtv (I know. I'm cheap. And Yes, they do make LCDtv).

Here's the thing. I don't need an a/v receiver, Just the audio. I found a couple of older receiver from my local Craigslist for around 50-70 bucks. Would it be wise to purchase them? I mean, some of them are 5.1 and some are just stereo receiver but that should be fine with what I am looking for. Again, I am cheap (or not really into full blasting my house). It would be my first receiver so I am pretty much just testing the water to see where I stand and what fit me. What are some good features to look for?

Some advice please. TiA. Please be nice. (oops. just realize we have a newb section. oh well.)
