Every USB tuner I've tried in the past has been at the mercy of the USB bus or external powered hub. If you have multiple USB tuners you should really use a powered hub rather than tax the internal USB bus to provide power to them. The only problem is that USB tuners have a nasty habit of dropping off the grid every so often, requiring that you rerun WMC setup to get them recognized again. Otherwise, they work just fine. The Hauppauge 950Q and the HP USB tuner (a rebadged 950Q) are both excellent USB tuners. The (AverMedia?) VolarMax USB tuner is also an excellent choice.
Picture quality from any digital tuner should be exactly the same since it's all digital. You either get the signal or you don't. If the signal is too weak or too strong you'll probably get some digital artifacts like pixelisation. The main difference between tuners is how sensitive they are to picking up distant signals. Some are also better at rejecting multipath interference.
Thank you! Glad to hear tuner brand/interface shouldn't affect PQ. That was a big concern of mine. I can do PCIe, and I have thought about the A188, but the reports of it disappearing randomly worry me. That's the last thing I need is another headache like that. I'll look into the 2250 though.

How I wish it was! That's something I could fix. Silicondust looked at my logs and said it's definitely a signal issue. I replaced my antenna, relocated said antenna, replaced coax cables, tried new power supplies, nothing helped. Frustrated and tired of throwing money at it...
