let's tease the Americans with limited availability of the cool stuff
Guys you have no idea how lucky you are in the States. For a start, Warmoth is there. I buy a neck - add $60 in shipping and then £60 (~$94) in customs to that price thank you very much.
Fender is there. Gibson is there. Seymour Duncan is there. DiMarzio is there. All this stuff, you're getting it way, way cheaper than we are. It's actually cheaper for me to buy SD pickups on eBay from the States and ship them over, than it is to order one from a UK-based online retailer.
Almost every single part for my current build has had to come over from the US. The one "big" thing that came from Europe was the super-super-switch, from Germany. That was about £25. The only other things I managed to source locally were things like a volume knob, and some of the electronics supplies (wires, resistors, stripboard but NOT pots). And it's not like I live in the sticks - I'm in London. There are plenty of guitar shops. They're just all extortionate.
Almost all of my supplies come with extra shipping and customs because they come from Stew-Mac.
[Also, my house is probably smaller than yours (two bedrooms, a lounge, a kitchen and a bathroom) and it cost the equivalent of $470,000.]
Appreciate it.
