I could do it for less than that (maybe a little over $100) with a universal kit from CX or and some couplers from siliconeintakes.com, I'll bet.You make up a portion of the price difference with the cold pipe solution for fost mani, though. like...$200 or more of the difference, from what i hear.
Looks like the CX kit for $110: Amazon product ASIN B00F3TNO10 (2.0mm piping).
Treadstone (a little nicer) costs like $180 for their kit, but it has no clamps and is only 2.1mm piping (essentially the same). I'd just do the CX.
