Oh I totally agree it's damn difficult in the USA, I was just curious really.
The only reason I mentioned NI contributions is when I was looking for a breakdown of NI, there are many references similar to this:

'The vast majority of public NHS funding comes from general taxation and National Insurance contributions'
I've no idea to be honest.
I've bought many USA instruments in the past, but from now on, due to the extreme prices we are seeing, I will be less tempted. I do have two full fat USA Bongos though (on topic!) and personally I'd advise going for one if you can.
