I have the slingbox pro HD. It has worked flawless since day one. I have a dedicated H25 hooked to it via HDMI and also use the integrated OTA tuner as a secondary source. I use my iPad and iPhone and MacBook pro to access it. Slingbox is a great piece of hardware and I highly recommend it. If you can go with one that supports HD and you won't have any issues with the new HDGUI.
