I use Musteks "TA IV" transparency adaptor with a 12000 SP+. Slides need
some gamma correction, overhead sheets are OK without.
In germany, it is sold for around DM 140,- by e.g. ATELCO - see
<http://www.atelco.de>. You could ask Musteks email support about
retailers and pricing in NL - they're generally helpful wrt this kind of
questions.

In principle, the TA IV isn't that much different from what you describe
and you could certainly try to build something like that yourself.
Problems:
- Would it be cheaper ?
- The right colour and intensity of the light is critical.
- Homogenity of the lighting is even more critical.
- Usual neon tubes flicker with 50Hz frequency, this could (?) cause
horizontal stripes in the scan. You may have to use a lighting source
powered by DC, not AC.
