I just read that D2Pro makers will be giving a new firmware sometime in the next week that will allow updates via DVD instead of the programmer. So...wait a month and buy it so you don't have to spend the extra money on a programmer that will soon be worthless.
I found this after submitting an e-mail to the tech support team of D2Pro asking that very question 5 minutes ago. I'll post what they reply back with as well to confirm it.
