Another vote for the Coolsat 8100HD here. The big downside is the lack of Blindscan, but the Fortec Ultra is covering that right now. It's easy to tell when the Fortec stumbles upon an HD signal, so I can plug that in later.
If you end up with one, tho, put the latest factory firmware on it ASAP. I had whatever came with it (from a dealer) and it acted like it was possessed -- no PVR, no Satellite selection, the motor moved randomly...it was ugly.
Oh, and the PVR works like a charm. I'd watched a few HD shows I've recorded and it looks and sounds wonderful. I recorded something off of Equity's FOX channel once and it reset halfway through, but that was an isolated issue and a FFWDed over to where it dropped off and continued. Also, it will split @ 4GB, but it's always cycled through to the next file, so it was a minor issue for me.
Hopefully more S2 and HD channels will come up in the future, making the box even more useful. Until then, it's a great addition.
