The AzBox units definitely sound interesting, especially the miniMe American Edition. If at all possible, please consider adding the functionality to make it work as a PVR backend for XBMC. If it could do that, I'd be much more likely to buy one! Although I suspect the biggest challenge there might be populating a schedule grid, since most North American stations don't feel the need to send any program data along with the signals.
Basically I am looking at this and at the TBS MOI, assuming they ever actually start shipping the thing and someone reviews it. But what I don't know is if the MOI will do 4.2.2. If it won't, that will really be a dealbreaker. Anyway, I'll just wait a while and see if one of those two actually does what I want. I wish the AzBox weren't quite so high in price (almost double the price of the MOI), because it looks like a really nice unit, but anything higher than about $100 is a bit rich for my budget.
I assume the AzBox supports DiSEqC and 22 kHz tone switches, correct?
I have a feeling that the next time I get a receiver I'm going to have to update my C-band dish feedhorn (it's still one of the old C/Ku units with the little blue polorotor thing on it) and also get a new positioner controller that can be controlled by the receiver (still using an old analog C-band receiver just to move the dish). It's one of those old 10' Winegard perforated metal dishes so with a modern feedhorn I'd probably not have any issues with signal strength on the C-band signals. If only half of the arc were not obstructed by trees that are not on my property! Seems like so many of the big oak trees are dying around here and yet the one oak I'd really like to see die never does.

I THINK I can still get that 91W bird okay but anything east of that pretty much goes away when the leaves come out. But anyway, it won't be just the cost of the receiver, it will also be the new feedhorn and positioner too, and that's a pretty big gulp to swallow all at once.
