I just got the Toshiba PDR 3300 (3.2 mpix) with a discount from that class action suit they had last year. It takes pictures at 2048 x 1536 x 72dpi and the only thing I noticed was that in low lighting it gets some pixel distortion. Haven't seen any freeware proggys that fix this very well, but if you have adequate light, you're ok. As for making the image larger, say 4000x4000x600, photoshop doesn't do a great job there either but I'm told that a plugin "general fractal" from the site above will do an excellant job of increasing the resolution and even cook your breakfast for you. The $150 price is cheaper than your $400 upgrade price.
