Thanks all.
Seems to be a general consensus that the older gear is the stuff to look out for. If, indeed, I decide I can't live without it.
Redstriper - no idea, I am afraid, but I'll ask the guy when we go there again next week.
Alexharvey - yes, I had a little peek myself - but with my eyes closed. There is a full rig on Fleabay as well... again, not that I am looking.... but, yes, I will do that exact thing next week - hire the rig again and mix and match the elements of mine with it to see if I can narrow down what gives the sound - the head or the cab.
Stevie - a heavy head is fine, it's those monster cabs I worry about.
Nick - that is what was so cool - the eq was flat. I think there were a couple of buttons pushed in, no idea what they did, but there was no fiddling on my part. Plugged in and Wow! Exactly how I imagined I should sound.
Keep 'em coming guys!
So how much is a 6 month old, gigged once Mag C210 EVO II 300 combo plus slighly older but good nick ABM 210 ext cab worth these days?.... not enough, I fear.
