A NEW ROSOTCK MINI OR KOSSEL DELTA (no replies)

HELLO,
Everyone.

I am wandering and looking for a DELTA printer. maybe ROSTOCK or KOSSEL.
i have a prusa i3 already. and i want to have a delta printer. i searched in the internet, it seems that delta printer is much faster than prusa printer.
Do you have a recommend?
I brought a prusa i3 from www.3dminions.com. They sell DELTA printer too. But do you have another printer. I need more options.

Thank you.
