As to the original question. Hondas are the most expensive out of the 3 but good reliable bikes. Yamaha is also more expensive than a Suzuki. Suzuki's have been number 1 in every class (600, 750, 1000) until this year (if i recall correctly) when the 06 R6's came out. Suzuki is cheap, I bought a brand new 2005 gsxr 600 for $7,000 out the door, where my friend bought a 2005 CBR600RR USED with 4500 miles on it for $7500.
These bikes are so fairly similar in performance so it all comes down to personal preference. Go to a dealer and sit on the bikes and see how you like them. As for me I'm a Suzuki guy, but I am lovin the 06 R6's..
