I like the BRZ but it needs more than 200HP IMO. Also Hypertech makes a plug in programmer that adds 26HP and 48 pound/foot more torque to the newer WRX's.
Fortunately there's a boatload of Japanese cruisers in that price range. If you just want to "cruise" I'd look at the VTX1300. It's reliable, easy to maintain and comfortable. If you want a little Go then I'd consider a Mean Streak, Warrior etc..
