A number of us are using Gazza's conversion kits to install replacement, hopefully upgraded light units in the std shell.
Choosing a suitable replacement unit is tricky though, as you don't really know how they will perform until you've actually bought and fitted one.
For this reason, it would be most helpful if you could report back on the performance of the motodemic unit.
