Weddingbee boards

Hello! I'm a newbie to the Gocco world and am dying to buy one. But no matter how hard I look online, I can't seem to find a chart to compare sizes of the different models. Please help! Anyone who knows dimensions and/or plusses and minuses to the different models please let me know. I want to be as informed as possible before I drop such a huge chunk of change for one of these babies! Plus, it's a great google resource!

Sizes/Dimensions/Pros/Cons:

PG-5

B6

PG-10

PG-11

PG-Arts

PG-Super 10

any others I'm missing? Please fill in the blanks! Much love to the hive! 

Correct me if I am wrong, but I believe all are the same size, except the arts is bigger (and more expensive).

PG5 and B6 are the same, with one being the newer model

PG11 and the 10s are the same, with 11 being the newer model.  These differ from the above b/c they have counters and registration plates that make lining up the print in the exact place possible (good for multiple passes on the same print). 

I'm also trying to get what size they print. Like, I've heard the B6 can print up to a 4x6 (and I  mean continuous print, like, printing one square of color only). What is the biggest size of a single design that each machine can print?

The link is good for basic differences, but I think it's still missing any hard and fast dimensions. That's my main concern, how large can I print? I've designed a wedding invite suite for a friend, and they have a color border all around. For a card like this I'd need to know maximum sizes. Can a PG-11 print continuous color over a 6x9 area? Or a 5x7? Or can it just handle smaller sizes? If anyone knows the answer, please tell me! I would greatly appreciate it

You inspired me to bust mine out for the first time.  I printed too close to the edges. It doesn't burn the screen well at the edges.  So, no borders.
