I hate to break it to you but any skates you get for under $50 are probably junk that you will want to be rid of after a dozen or so times out on them.

If you shop carefully, you might be able to find a better pair at one of the big box sports stores (Sports Authority, Dick's, etc) that has been marked down for clearance.

Other than being really likely, you are probably looking at around $100 for Rollerblade or K2 skates.

You really should also get a helmet and pads. A bicycle helmet is good for rec skating.
