Looking to build a 3D foam plane what do you guys recommend?
I'd consider the Revolto from Twisted Hobbys to be near the top of the list of good 3D foamies. It's definitely my favorite foamie. It's similar in size and weight to a Sabre 35, and uses pretty much the same electronic gear. But the Revolto is a MUCH looser plane than the Saber 35. Lots of fun for experienced 3D pilots, but might be a nightmare for beginning 3D pilots.

The Giles 202 from Value Hobby is also a nice flying plane. It's much smaller and lighter than the Revolto, and costs only a fraction of the Revolto. If you have never had a 3D foamie before, this is the one to get first.
