Congrats on the new ride. I looked at the FZ1, ZRX and Bandit for a number of years. I had an '83 Yam 1100 Maxim saddled up during this time. I went with the Bandit based on price, powertrain reliability and really most of all - comfort. The FZ1 was fairly expensive in comparison but fit me well and although I really like the ZRX a lot I found it to be least comfortable for distance.
I had a concern with (some) Yamaha transmissions... Although it never failed me I had a balky 2nd gear on my low mileage Maxim - it sometimes shifted real hard or missed 2nd gear (especially when the oil was end-of-life). My brother's YZF600 blew out the 2nd gear with very few miles on the bike due to the shift dog issue. I read as much as I could on bike transmissions and would say that Suzuki was best in this regard.
