No, that's not a good price. Sorry man, I'd say pass.
Agreed. You can do better if you are patient.
+1, $850 is the going rate for this amp.You shouldn't pay more than $850 american for a head in decent shape.
It looks like 800's are still going for ridiculous prices. People are usually looking for early (81-83) 2203 and 2204's, and later 2205 and 2210's. I bought my 2210 for $800 a couple years ago, and prices have went up since then. I've seen some 2210's go for $1000 to $1200.
If i were you I'd wait it out a bit.
I've found, from past experience, if you have to ask yourself wether it's a good deal or not, it's not good enough. Now if you look at the price tag and go "hot damn!", then odds are, it's a good deal.
