On a purely dollar per watt basis, those are not going to be winners. Your better deals are usually found in the larger panels targeted at the grid-tie market.
For example, take a look at this one. It's a 340 watt panel for $250 (plus maybe 30-ish for shipping). That works out to a delivered cost of 82 cents per watt vs $1.65 per watt for the ones you pointed out. Mind, these would require an MPPT charge controller to attach them to a 12v battery bank, but that's not really a bad thing in my mind, and the higher panel voltage (24v+) will mean less power loss on your wire runs from the panels to the charge controller.
