I tried a cornell romany plus recently, and I really liked it. Now, the disadvantages are (a) it's not a head and (b) it's quite dear.
But it sounded awesome. it's 10 watts, and has a switch to set it down to 2 watts, and then 1/4 watt (though the one I tried only seemed to have two power settings, "loud" and "soft").
Worth a look, at least. I was very impressed.
