I am based here, I can help with gear prices but as I recall (from friends) GH is pretty expensive here.
Are we allowed to discuss prices on here 
PM me if you like
Prices are fine here is my understanding, Posting up soures of AAS of a NO No...
Also, I'd avoid any Internet venders out of Thailand. If the DEA recently popped one, they will be back for more... Understanding how protection works there is alien to the western mind.
Intnl politics are at play here, what/ who thought they was untouchable is in for a rude awakening..
Local protection goes out the window when the Nat forces get prodded with money, or threats of loss of US$ funding.
Bottom line, If your a US citizen and want Thai gear, I'd go there and use it, not order it.
