I can definitely relate (see signature). I'd really like a Ducati 1198 now, but I would still have to have the other two bikes because they all serve a purpose. But I really can't afford a divorce right now!
I'm probably going to get flamed for this, but my last 6 bikes have been: '01 Wing, '02 Wing, '05 FJR, '07 FJR, 08 Concours, and now finally another Wing because I have a lady friend who likes to ride with me and there is nothing better than a Wing for 2-up riding. BUT, I already missed the sportiness of the other rides and so I went off the deep end and bought a Suzuki B King. To me, it's a Hayabusa without the pain, and since they didn't sell very well, I got mine $4k off MSRP. So, now I've got the Wing when I want sanity and serenity, and the B King when I want to go crazy. I hope I don't kill myself on the damn thing.
