Compared to the vPod, I find John's latest offering extremely non-expensive and surely not over-priced, seeing that the hardware alone will easily cost 30€. And as we all know, software development for a small market is expensive.
The missing RO6 drivers are a problem of course, but have ViewFinder users really "up"graded to RO6? After all, most of the cool ViewFinder features are no longer available there. So I guess it is more of a problem for ROL, who still have not properly documented the ViewFinder driver's state of RO6 on their website.
