For about US$350 you can do a very professional installation of the Rostra Global Electronic Cruise Control, which works just like a car's (and better than the California 1400's, since it allows incremental speed adjustments). This should be a consideration when pricing a new unit.
The installation is on an 1100, but should also work on the 1200. The servo unit goes where the evaporative canister is installed on US models. To find my detailed instructions (with linked parts list), just google "rostra GRiSO" on the interwebs. I suppose I should make a more concise version by omitting the discussions of design decisions. The actual work involved is not too demanding.
