I suggest that you keep a bookmark of
http://p092.ezboard.com/fsawatdeeforumfrm74 which is the old Sawatdee Forum. The resistance forum keeps one up to date on the latest proxy.
Most of them are between pretty slow and excruiciatingly so but I found one today
V3 Proxy to Sawatdee
This seems very fast but for me I don't get all the buttons e.g. edit on Firefox browser.
