Not sure what to make of it. The 45lb weight limit is a bit worrying, though. The BoB Yak, the closest model to this one, weighs in at around a pound heavier, but has a 70lb weight capacity. The difference may well be in the hitch systems -- the Nashbar one looks to create a fair degree of leverage on the dropouts, whereas the BoB one keeps its stress well inboard or close to the dropout.
Still you get what you pay for, and at less than half the price, the Nashbar deal might be too attractive for some. For touring, I wouldn't consider it. For commuting for shopping loads, the weight capacity limits it, and for 45lbs I would use panniers.
