you can get a marshall DSL401 used around ebay etc used for 400-600 and they have a great tone, 40W sounds like it'd be loud but it's really not that loud, and the recording direct out is pre master volume, so you can plug that into a mixer, or PC, i don't think it'd drive a pair of head phones on it's own, but it's a line level output that is pre master, so you can turn the master volume down and mute the speaker and have the direct out unaffected, but even so, it's not a "loud" 40 watts, i can turn it up 1/2 way in my living room comforably with my mom in the same room, and she don't bitch :-D so it's not LOUD loud

alternatively fender blues junior pro are decent sounding amps, and low wattage, can be had within you price range, also the fender deluxes are decent low watt amps but those are a little more pricey.

blackheart amps i have no experience with at all
