... what currently produced Speedlite (or a competitor) would do the job well at a lower price than today's crop of do-everything-automagically-with-remote-control flash units? What I need is a head that can be pointed anywhere and a fairly simple auto-exposure system that would function with my 7D.
Well, it's a do-everything-automagically-with-remote-control flash unit, but it also has a head that can be pointed anywhere and does eTTL-II: the Godox TT685C
. You can find it new for $110, and since Godox is a Chinese company that doesn't actually do customer support, getting it from Adorama or B&H who will support it themselves might be worth pursuing.
The reason you can find so many 580EXII and 430EXII used (and those are also great options, and arguably better options if you never plan to take the flash off the camera and go Strobist
), is that Canon came out with the RT radio-controlled gear.
Godox's gear is a cheaper alternative to the RT system, with some key differences that make it a very popular system. The Godox TTL/HSS lights support TTL/HSS cross-brand for six brands (Canon, Nikon, Sony, Fuji, Olympus/Panasonic, and Pentax), so you can share lights if you have, say, dSLR and mirrorless gear, or want to share a lighting setup with someone who's a non-Canon shooter. And the Godox system
also includes larger-than-speedlight options, such as studio strobes, if you really get into lighting for portraits. But neither of these factors may be of interest to you.
I own both a 580EXII and a TT685C. To me, the TT685C is a weird halfway point between a 580EXII and a 600EX-RT clone only in Godox's 2.4GHz system vs. Canon's. I use my 580EXII for on-camera event stuff; but I'll grab the TT685C every time I might need off-camera. The TT685C also makes a terrific backup unit to the 580EXII, and can do Canon's optical wireless master/slave modes, too. I prefer the Godox radio signalling, though, because when I'm not using my 5DMkII, I'm grabbing a Panasonic GX7 or a Fuji X100T, and the TT685C can be a TTL/HSS/remote power slave to all three camera systems.
