[Bärtschiger Urs]

Thanks a lot Jim and Earl. I'll be getting the E-Logger. Didn't know this 
unit before. Thanks again!

I agree with Earl.  If you can't handle the full data logger go for the E
Logger.  I understand Eagletree will have a hand held read out device that
will eliminate the need for the laptop.
I also use an Astro Flight Whatmeter or whatever he calls it, but I'm
putting the full Telemetry system in my Impact.

The Micro-Power E Logger
(http://www.eagletreesystems.com/MicroPower/micro.htm) is worth
consideration. It logs relevant E parameters and has the capability to log
other things as well. At 17 grams and $70 it's a pretty good deal. A
PC/laptop is needed to analyze the data. While I haven't used this
particular unit, I've experience with Eagle Tree Systems other units and
their excellent service.
