I look at it in two ways:I'm wondering if it's worth getting something fancy.
1) If the amp in question gets you your holy grail tone and it saves you from spending significantly more on a series of GAS inspired dead ends ampwise then yes, go for it.
2) Amps don't have to be very complicated or esoteric to be good, most of us have a grail tone based on something we've experienced. Only the fool hardy would slap down big bucks without trying something first. I have a couple of 5E3 clones which cost 90 quid each and for 90% of my needs, they're perfect. Then there is the gassing for something Super Champish or 90's Mesa Boogie just for playing pleasure. No way I can justify it as a non gigging player so I make do with pedals.
