R1200S in red and silver stripes is the hottest current BMW, imo.
The R1200ST would likely be a very good bike, too. I don't find them too offensive personally, and they look immensely useable.
The R1200R preview images have looked very nice, too. However, if you're keeping your Triumph, it would be somewhat similar as an open roadster.
Myself I'd probably wait for the F800S or ST bike, which should be here in the State for 07. Hopefully the new F's will be priced affordably; BMW's are a bit expensive to me.
