Lightweight Flywheel

[boab type ra]

ma gearbox broke after the monthly meet on thursday night so need to mine repaired or put another in, anyway i`ve got an exedy hyper single at the moment but its too hard to use every day so i was thinkin of changing it when doin the box. i seen this on ebay but its a bit cheap to be true can anyone recomend it or somthing better but resonably cheap.
