Maybe a secret that I shouldn't give away, but..... here goes.
I signed up to
www.myUS.com about a year ago. Essentially it gives you a postal address in Florida, enabling you to have things sent to you when either a seller won't ship outside the US, or a dealer can't due to manufacturer regulations.
It's not super cheap (about $10AUD a month, plus shipping usually works out around $160 from US to AUS), but it enables you to grab some really great deals off US ebay/GS etc. Everything is sent via DHL, but they are big enough to get something like 50% off DHL's published rates. They'll also hold your items for as long as you want and combine multiple items into one box to save on shipping. I generally purchase one big thing, and then stuff the order full of little things and send off.
Things on US ebay that are open to worldwide bidders almost always go for more than local sales, so it's pretty cool to have.
Re: warranty- to be honest, most dealers or distributors here are horrendous. I bought a new $4500 guitar with a busted case- the shop promised to replace it as a condition of sale and never did despite a lot of hassling, I think I got a free set of strings (on a RRP $250 case). I've bought pedals that have broken within warranty period- retailers have charged me (!!) to ship them to the repair shop, who decided they couldn't find the problem, despite the retailer agreeing it was broken.
Guitars I've had have warped within 6 months only to get "Oh, that's not a problem, Spanish guitars are meant to do that". It doesn't play in tune anymore, that is a problem.
For my experience, 9/10 a warranty isn't worth the paper it's written on (as highlighted by the Taylor thread on this site), so I'd rather get the items cheap for when they inevitably break- I can spend the cash I've saved having a real tech getting it working again.
