Wow, that's really cheap. Fair enough. But to play devil's advocate... OP already has (assumingly serviceable) Shimano cassette hubs. High quality, double butted, stainless steel spokes can be had from Yellow Jersey bike shop for $60 plus whatever they charge for shipping. I found some Sun Rims CR18 rims online that can be had for $64 shipped. So for around $140 the OP could have a hand-built wheelset that I'm assuming will have much higher quality parts than a $100 Niagara wheelset.
