Here in the UK, Euromix cabs aren't a rare find at all - in fact, ZIV lists the vast majority here, while they're about as rare as a Beatmania cab for us everywhere else.
I haven't played on one of these in probably, like, 8 years, but there's a reason Extreme-style cabs in good quality are still sought after.
I'm not picky, and neither should you be, honestly!
If you have the opportunity to try out a Euromix cab, especially if you're used to the newer games, I'd say go for it.
As much as I'd like to, I can't defend the western X cabs.
These cabs are known for their absolutely horrible pads - no brackets, no way to feel where you're standing (which is the main reason I love arcade pads), as it's all covered up by a gaudy metal sheet.
These cabs are playable, but barely. Unless you are lucky to stumble upon a modified cab with the overlay sheet removed or you don't have any other option, I would steer clear.
Sadly, picking and choosing is not often a luxury players in our region are afforded.
I haven't played on one yet, but I've heard great things about the white and gold cabs!
