Maybe I don't get it but the teleskop austria device is 89,- euro, incl. cable, box etc. plug&play Listed on their site for 99,- eu but the introduction price is 89,- euro. No need to find a box, soldering etc....... Shops are closed now for one week.
I agree that it is the best of the Tronisoft alternatives for European customers but things may look a bit different from a US perspective for people with some DIY skills.

I really would appreciate explicit instructions. I really should be better at electronics, considering my background with them, but I am decades out of touch, really. Certainly, I am not afraid to solder things and get my hands dirty.
I don't have much confidence or experience with this stuff either, but found the bluesmirf easy and reliable too. No configuration issues with papywizard and my nokia 770. (Brewzone is my blog.) You might like to look atJason's description He used a spark fun power supply kit that cost $10. It requires more soldering, so that's why I took a car power supply that output ~5 volts - pre assembled. You probably are going to need to solder the cable anyway...
The input voltage requirements/tolerances for the bluesmirf are on the sparkfun site. (Or any of the other robotics sites that carry sparkfun components.)
