I don't know which model it is, but it doesn't seem like 171s. Perhaps there *was* 170s model.
Although the physical appearance suggest same model, the specs says otherwise.
Brightness and Frequency is different- 171s model is superior
Contrast ratio, oddly enough, is better(?) on the 170s model that Sam's is selling...
hmmm.... it's tempting, but i think i'll wait.
thank you for the heads up, though
