Which 3d printer to use for prototyping

Hello! I am looking for 3d printer to print prototypes for future manufacturing. When I was searching via web I get something like this list, which shows really expensive printers. I think this is too much. I’d like to print something around 20-30 cm.
I was thinking about K8200, but as i understand it’s only up to 20 cm.
Could you please help me to make a choice.
Sorry, English is not my native language.

So far i know, all the 3d printers from Velleman, do not print above the 20 cm on the bed, the Delta K8800 can till 22,5 cm high.
So look on to other and google around.
