Well I got my APX skates on eBay for $650 brand new, and I got my chassis for $21, so it was cheaper for me to convert than to buy the APXrs. If money wasn't an issue, I would prefer to convert them, simply because I think ice boots are constructed with better quality. And if you really like sprungs, then I would suggest converting the APX or TotalOnes. The APXR's do come with a new set of wheels, frame, and bearings so I guess you would save yourself the trouble of spending money to convert, the price of the chassis, and the price of wheels.
