How good can it be, if it isn’t HD?

With my CableCARD tuner coming tomorrow, I’m packing up one of my Series3 TiVos to sell, and I’m looking for a Media Center Extender. All three options are about the same price, but right now I’m leaning towards the D-Link DSM-750 even though it’s the most expensive at $315. But I’m tempted to save some money and pick up the Linksys DMA2100 for $250, but Chris L’s review has me thinking twice. The real problem is that no one has reviewed the D-Link. The Xbox 360 is $300 after you buy a remote, and although I understand it makes a great extender and also plays games, I’ve had one and the noise really bothered me. Plus I hear the IR receiver on it is troublesome.
