Seeing as you mention "Dance / Electronic", I would have to say that Nilz at The Exchange pretty much rules the roost on that one, and I can say that in the knowledge that few of the vinyl cutters here will argue on that score:
http://www.exchangemastering.co.uk/I've had 12"s cut from Nilz, Mike and Graham. I would describe Mike's sound as being more "laid back" than the other two, and his portfolio represents that, i.e. he is famous for cutting LPs and 12"s for the more jazzy dance labels such as Talking Loud.
Graham can cut either. The cut he did for me was a scorcher, a bit like one would associate from Nilz.
Nilz is famous for blowing cutter-head fuses - he is the peak volume champion.
Note that none of The Exchange's MEs advocate compression, unless you really pressure them. I can think of an occasion with Nilz where I wanted some squash and he talked me out of it.
You won't have any problems with
John Dent either - he is very dependable and regularly receives plaudits from contemporaries.
If you venture abroad, then make sure to try Paul Gold, as Brad suggests - he is highly respected by the NY dance labels.

edit: Just to be sure, don't get the impression The Exchange will default to nuclear loudness - they will cut exactly as you ask, and can cut very 'hi-fi' if you ask - it's just that they've attained a reputation for pushing the peak envelope that little bit harder because the industry has demanded this in recent times.
