They're not that cheap, price point will be somewhere between MCR320 and PA120.3 (for the triple version).
If performance comes in somewhere between the MCR and PA then its just another rad to consider.. They likely are not going to ship with all the bling of a TFC (Silicon Pads, Barbs, Compression Fittings etc).
There isn't a 480 model, It would be nice if that came sooner rather than later.
