Throw Innovate in your list to look at.

One of the downsides of the WEGA when I was looking was it is limited to 3 channels. A/F, rpm, +1 analog.
If you are looking to log for a turbo, you'll want a/f, rpm, boost, tps, injector duty cycle, and maybe fuel pressure.
A DL32 will log all of that (with the LC-1) and is expandable up to 32 with add ons.
Downside, price compared to the others.
I think the WB adds another analog sensor to that. I know of a couple that have went from a wideband commander to Innovate because of the flexability.
Another that some of the locals racers run around here
http://www.rpmperf.com/ (they are located here) but I don't know a lot about them.
I'm picking up A/F, rpm, tps, gps, injector duty on mine. Wiring the fuel pressure this week and I'm looking at clutch logging solutions right now. I'm using a DL32, LC-1, XD16 combo. Future expansion was the main reason. I didn't want to out grow it. I am disapointed about how slow product development has been, but other than that very happy with the unit and tech support. (phone support as the support forum is not really worked that well)
