True. But really it comes down to what you want the amp for. I think the clone I built is better than my 82 800. So yes, you have to decide what is important to you and you have to really like the sound, not just the idea of it.Marshall isn't even making reissues of those 75-81 JMPs. If they did, I can see the originals not commanding so much. But the originals are really the only real Marshall version of those amps you can still get. Plenty of clones will get the tone, but not retain their value over the long term.
