I'd buy the VP for 2-yr warranty, faster output and other features.
Chad, you can get more output if you willing to spend some money to do so. I get 64 SFPH @ 720x720, which is exactly 2x the speed posted by Roland. Still, it's no speed-demon that's for sure. I made a banner profile that yields about 160 SFPH, but the quality is marginal, but sellable for the right kind of job.
