The PCH A-200 does seem to be the best of the bunch, at least on the list I made. But costing almost twice as much as the WD TV Live, is it worth it?

I've read negative comments with regards to the Xtreamer Sidewinder's LAN connectivity having some performance/speed issues (other than it's just 10/100 mbps). So that's out.

For now, it's a toss between the WD TV Live and the PCH A-200.
