Is it Worth $300 more for the 2nd Gen Solidoodle?

You mean 2nd and third generation because they don't sell the first generation anymore .
SD2(2nd generation) and SD3(3rd) are the same printers the only difference is the size, you can print bigger models with the SD3.
I think(but it's only my opinion) it's better to buy the SD2 because it dosen't cost much and for the price you can print big enough models .
As far as I know the 2nd generation is far better than the first.
