Just go to rollerwarehouse and poke around, I got trs downtowns which are Rollerblade brand. They aren't the hottest new company but they are tried and true, they'll get the job done and mine cost like 150. I guess you could hunt down a used pair somewhere, actually look here in ski equipment I think I saw some quitters in there selling their blades.
I'm a firm believer that if your not that good you don't need good shit, I used to hate seeing kids who could barely skate with brand new expensive top end shit.
