The best match would be a second AF100. If you're wanting a normal camcorder-style camera, I'd recommend the AC130, as it has a basically identical menu set and operates pretty much identically to the AF100 so you'd have a very easy time going between the two.
A used AF100. Seriously, they're going for around $1000 now. No fussing to match.
HMC/HVX/HPX170 are also decent choices if you don't need any low light ability and could use a small sensor servo zoom cam. AC130 would also do, but chances are slim of finding one less expensive.
