I have the PC Cinema which came from TigerDirect. The whole outfit cost $1300 including IR mouse and keyboard (which are from Airboard. ) I have seen these at computer shows for $20 and $40 respectively.
They work well and have the added benefit of being comaptible with my Pronto.
The have since stopped carrying it. You can search the web and find the original manufacturer Base Technologies.
I bought a Denon AVR 3600 at Ubid for $700 which has worked flawlessly. I have since replaced the MB so that I could get more speed. The original came with AMD 233 and I now have a Celeron overclocked to 374.
Definitely get the Pronto as a remote, it kicks. I have since replaced the keyboard with the Logitech RF modle which works great. So I have RF keyboard and IR mouse and IR universal touch screen remote.
Recently have been thinking of upgrading the video card to the ATI Rage Fury 128. When they have good digital VCR software, I probably will. That way a big hard disk and new card could subsititue for a Replay or TiVo.
