I believe I'm in the same boat as you jackal. Also looking to get my first printer and have decided on MakerFarm i3v based on reading a lot of posts on this forum. I was about to pull the trigger on the 10" but then the 12" came out last night...

The only other thing the 12" version has besides a bigger build area is the graphical LCD interface as opposed to just the regular LCD interface. I do not know whether this is as important an upgrade as the bigger build area is, hopefully an experienced user can give their opinion on this.

The price increase from the 10" to the 12" is $60, compared to $50 from the 8" to the 10". 10 extra bucks for the graphical LCD seems like a good deal as they are sold for a $60 standalone upgrade.
