apacI found the 1800 DA for 29 dollars new on ebay

What is the difference between this and the newer version, does the increase in dpi really matter?
I quote
"Razer Deathadder (3.5G>3G) Must use 3G at 1800dpi for proper tracking. Requires latest firmware to remove prediction. Has a high lift off distance that can be fixed by putting a piece of scotch tape on the sensor."
