Here comes sage advice from someone who was in your shoes.
I LOVE my S3 and if I can only have one bike this is the one I want. Hands down, nothing out there comes close.
However, I WISH on a freakin STAR that could have, would have kept my TBS. I had a '98 model and I sold it last summer after buying the Triple. Wife said no to two bikes and I caved in and sold it. I should have grown a pair and kept the bike.
I kick myself ona daily basis for not keeping it. I honestly think the TBS is one of the BEST all rounders ever made. It's got plenty of power, handles well, has looks for days and can ride anywhere. It's reliable. I rode mine with the sport bike guys, Harley guys, I toured it to the beach and back a few times. I cruised town and ran errands on it. Everywhere i went the old timers wanted to tell me about their 68 Bonnie and the girls wanted to stare.
I miss my TBS............................................... .....

So , mral of the story DON"T SELL THE BIKE UNDER ANY CIRCUMSTANCES!
Buy an S3, you won't be sorry in the least, I promise. But you'll want to keep the TBS for those, not so S3 days.
