If you're going portable, I would go with a DGA Mach Lite hands down. It's a great basket despite being a collapsible portable. I bought a Ching Chainmaster for my "portable" (28 chains in two rows), and it's the best catching basket I've used. It is pretty heavy, takes up a ton of room in the trunk, and is quite a pain to carry anywhere though. If I had it to do over again, I'd go with a collapsible basket and just be careful opening and closing it since it's not entirely metal.
I wouldn't hesitate to recommend a Chainmaster for a backyard basket though. The rolled chastity belt is much nicer than Innova's, and it really does catch amazingly well, especially for the money.
