I just got a large pistol case for $25 or so at a sporting goods store. If you do that, you have to cut the foam to fit your TXs. That Hobbico case at Tower Hobbies comes with uncut foam as well... it shows neatly cut foam in the picture, but the description says it's uncut. I don't know of a neat way to cut the foam. I used regular scissors to cut mine... it looks rather sloppy, but works great!

If you want a case with foam already cut, Futaba has a dual TX case... for about $80! It looks like there are two foam compartments in it ant the TXs stand upright in it...
