I have one of those too, and for the price I've been very happy with it. My only real objection is the amount lag, but it's only really noticeable when web browsing, and even then it's just a little annoying at first.
In case you haven't already, make sure to turn the sharpness and noise cancellation down. It'll make it look a lot better. Also, if you look online, there are other firmware versions you can flash to speed it up.
(The $330 deal was a $399 TigerDirect with a $70 MIR, free shipping, no CA tax. Ended Monday, but I'm sure it will return.)
