Marshall Amps (sub 100 watts)

I'm pretty sure that it's the Marshall sound that I want to buy for my next amp (sub 100watts), but there appears to be a rising consensus that the newer models (particularly the MG series) aren't worth the metal they're made of and that the tone everyone loves comes from vintage Marshalls or modded high end(price and wattage) Marshalls.

I'd just like to get a feeling of what you guys think about them before I go spending my cash for Christmas on some of the opportunities that keep jumping up.
