The voltage difference keeps me at bay. Yes, I know they can be converted, just don't feel like fooling with it, as do many others.
I always preferred in a weird way the German version of Fireball. I would probably pay a premium for that if seeking one.
On the flip side I purchased a Williams Merry Widow that had been stored for years in Sweden.
I assume it was in such great unplayed condition because it sucked and was quickly pulled.
However they didn't abandon it, wherever it was stored was dry and climate controlled.
Really in many ways the best OEM condition EM I have ever owned.
