Which Guitar Amp Should I Get?

I have been playing guitar for almost 6 years and its time for me to upgrade to a tube amp. I am looking for an amp that i can find for 500-600 bucks new or used. I play mostly clic rock, blues, and jazz. I want an amp that i can use to get a Clapton sound, or a John Mayer sound, or a bluesy sound. I don't need an amp that has crazy distortion, but i would like one with a decent overdrive channel. I have been looking at the Fender Hot Rod Deville. Is this a good amp for me? Please offer advice and suggestions for amps i should get. Thanks
