Think of it this way, you'd have a REAL one and one that will definitely hold its value and very likely only continue to go UP in value over the years unlike a clone which will only continue to go DOWN in value.
For me to buy a real one would cost alot of money... there's one on eBay (an Airline one, in London) for £850 - and here that's alot of money, and even more so for me and my small crying wallet (albeit for something that doesn't show up over here very often)...
And I actually enjoy making things myself, and this circuit looks like it could be a good first amp build for me - one which I'd probably keep for myself rather than hold on to and sell...
Could it be possible for you to perhaps record yours or even a youtube video? I've only heard it on that one YT video, and would like to hear a bit more of that clean sound etc
