I totally agree with teflonmyk, you don't need to go crazy on the dpi to get an extremely good image. In fact, many people in professional graphics and photography only use 300dpi or max 600dpi for everything they do, scanning and printing. Mostly because the image already looks about as good as it will get once it's been printed, partly because both scanning and printing take MUCH less time at lower dpi, and partly because at higher dpi your file sizes become way too big especially if you have alot of them.
Personally I scan at 300dpi, but then I print selecting a medium-high type print quality setting. My printable DVD's come out looking great. With either of these printers, the quality will be heavily dependant on what media you use. I have an R200, I buy just regular Epson high quality inkjet paper (100 pack is only like $12 or something) and the prints turn out quite nice. Basically with the right paper, either printer will kick ass.
