I'm curious as to why you want to acquire a 2D vs another model. I have both a 5x7 2D project camera and a very sweet whole-plate Eastman #2 (lighter wood than the 2D - D is for "dark" - but otherwise identical I think). I've migrated towards the whole-plate format but still, that #2 is a fairly bulky beast.

Another one to consider is an Agfa Commercial View with a built-in sliding extension rail. You could probably find a nice example around the price you'd pay for a 2D. I think the Agfa is a workhorse but easier to lug around compared to the 2D.
Personally, I'd go for a 5x7. They are considerably smaller than an 8x10, but not much bigger than most 4x5s. And you can always get a reducing back for them if you desire the smaller format. My 5x7 Deardorff Special has been my go to camera for years.
