I've just got back from there.
There's a decent shop in Wan Chai (Hong Kong Island) called Tom Lee music. Relatively close to the Star Ferry terminal.
They had a decent stock of Ibanez, ESP / LTD, Gibson and some PRS. Lots of Epi's too. The prices are generally a lot better than UK, given £1 = 15 HK$.
The pedals out there are expenisive, but I got a decent Planet Waves tuner for £32. They're doing 20% off for Xmas.
Luckily their site is in english too.
