Tube amp recommendation

My current amp is dying and therefore I am in the market for a new amp. I got my current amp back in my university daze (solid state, over 10 years old and cheap). Perhaps I should have upgraded years ago, but it served me well and I was happy enough with it (and spent the money on records instead).

I have always been impressed by the sound that tube amps generate and hence believe that my current amp is giving me the push to go finally into the tube world. I have read various items on this website (and a few others) and have a bit of confusion (and hence some questions).

Now pieces of information about me...
1) I like to listen to large assortment of music (old skool reggae, bad electronic music, the occasional rock record, various jazz items, sometimes even hiphop). Often I listen to stuff in what seems like an random order.
2) I am rather lazy on my days off (when I listen to music most of the time).

With these two points I mean I don't really want to change a set of tubes because my music selection is a sometimes bit schizophrenic. I don't want to manually adjust bias settings every Saturday morning (occasionally fair enough).

Therefore, can anyone recommend any tube amps that are in the entry - mid level for me?
