Hi, I'm new

I'm looking to buy a brand new 15.1Khz arcade monitor to mount in a cocktail cab I'm building. I've looked at the Vision Pro and Wells Gardner monitors Happ are selling, but both 19" models specify horizontal / shelf mount only.
The Wells Gardner site sells a 19" Universal mount monitor - which I guess (?) is more what I'm after, but since I'm in the UK i'd rather find a UK supplier than have to ship something from Illinois.
So, can anybody recommend a specific 19" monitor for use in a cocktail? What do you chaps who own cocktails use? If anyone knows a good UK arcade monitor supplier, so much the better!
Also, on a side note, does anyone know what I'm going to need to power it in the UK? A stepdown transformer? Any special cables? Am I right in thinking a brand new monitor will NOT need an isolating transformer?
Sorry to be so newbie-ish, but I've not had much luck in finding definite answers to these questions, and I don't have any cash to waste! Any help will be greatly appreciated!
