If you want all those different amp tones, maybe you should be using a modelling amp. Just sayin'...
Yeah, I first thought tweedier Fender, which have more of a midrange push like the Marshalls. You can't get the sweet SRV cleans though... Price range limits you a bit too. Maybe you should try something like a Hotrod Deluxe and tailor your pedals to give you the wider range...
BTW - on the Swart, don't forget that some models you can change the valves to different types for different tones. Not live though and more than a little out of your price range.
And yes, second hand is always an option on a budget.
