When I desperately wanted to buy MK Signature, I managed every time to find decent one with nice price around ~1300 dollars.
Don't know how about you, but I'd never spend 1800 Pounds, which is >2500 dollars by the way on a Strat. It's a Strat! A regular Strat.
Utilitarian thing. A lot of screws. Interchangeable parts. Why this thing could cost so much without being genuine custom shop or vintage?
Just because it's no longer in production? Still, I was managed to find decent prices each time. It's up to seller, if he is a bad guy, so price is inconceivable.
