I'd probably buy an old Swing-A-Way (Maybe one from the 1960's - 1990's) on eBay, if looks in good enough condition. You can throw it in some Evap-o-Rust (or similar) if it's a little rusty, clean it up with some brass/bronze wire brush.
The new Swing-A-Way brand is pretty much junk. The design is roughly the same, the Swing-A-Way name is stamped on it, but the materials and durability are inferior. (Par for the course, these days.) I did some quick research and apparently the Swing-A-Away brand dissolved in 2009, name sold to AMCO (not sure who they are), and now is manufactured overseas. Frankly, I don't care where anything is made...but this is the typical case of *buy rights to trusted old name, sell cheap shitty product until people catch on, rinse and repeat*.
