| ST4s Model changes
Hi all, looking at buying an ST3 or ST4s in the very near future, and have some of each model in view,but can't make up my mind which.
What are the model changes from year to year on them ?,I know the ST3 has changed '04 to '05 ,but what if any changes have there been since the ST4s came out ?
