Looks like the cheapest I could find for the HDFury2 from a known vendor is $142 from MonoPrice .

One benefit of the 990's DVI switching is that you could actually use the HDFury2 with two HDMI sources (with the 990 between those sources and the TV). You'll need to have two component inputs on your TV to do this - one for the component output of the 990 (for all your analog video sources, including that outboard HD tuner) and one for the component output of the HDFury.

If you only have one HD-capable component input on your TV, you may still need to locate the HDFury in front of the 990, at which point it would only be able to serve multiple sources if you added a separate HDMI switch.
