Neal - have a look on

It looks cool - isolation platform for camera / electrics and it's quite a bit smaller then the TBS - so smaller props / lipo's etc (cheaper

)
Also - the GoPro can be in it's protective box - which is a bonus.
Footage from these things looks very stable and jello free. Quite fancy one myself when I can afford it....
