There still seems to be a cost imbalance using a Pi ($40) and a Beast ($400), but I do suppose the beast gives the input sensitivity but for less expense than the RadarCape - $400 is more than I'd spend.

Just been looking at the Odroid U3 - looks v. Interesting (might get one!), I wonder if it would have the same problem I had with the BeagleBone black - that the USB did not seem to have enough power capacity to run the NooElec (sp?) dongle - and would need a powered USB hub in the config, the smaller square dongles don't get as warm so may be better in that respect.
