For the Malaysians, the late Tok Raja of Kelantan made some powerful pidtas but they are now very expensive. And there are many fakes around too.
For the Thais, please refer to the Benjapakee of Pidtas, namely the 5 top metal pidta makers, and the 5 top powder pidta makers. These old amulets are also very expensive. I have a few, especially LP Aiem if Wat Nang, Bangkok, LP Ta of Wat Panaeng Thake, LP Doem of Wat Nongpho, LP Keaw of Wat Kruawan in Chonburi, etc. I lost one from LP Ding - somebody pinched it. These are the top pidta makers.
There are also some top present day (or recently passed away) masters around. The bros and sis in the forum may be kind enough to reveal their amulets to you.
I think I saw an article or something about the top 5 pidtas in a website - possibly Montien Plaza website. This is a Bangkok shop. I tried to find it without success last year. I have a feeling expensive and deal in top of the range amulets.
Different master, Different wicha, Different purpose. Different people got different preference. Me being a Tok Raja fan/devotee i would die die say Tok raja but ltr another LP Toh die hard supporter/devotee come out n bash me den this thread got war redi. So rather dun compare Guru monks.
Ya for Kelantan tip top no1 pidta sure will go to Tok Raja Pidta.
But pricing is damm sky high and due to alots of fake. U think RM1888 Tok Raja pidta in ebay or in FB is genuine meh? And not many people can identified genuine or fake. (Including me also, i still dumb)
If for more baget, can go to Than Chan (Tok disciple) or others Tok top disciple's pidta. Or maybe LP A1 wood pidta or PT Soon pidta also good choice. More economic to wallet also.
My personally wearing PT Lek (Wat Aril, Kelantan) 6 hand Maha Ud Pidta. This Pidta very good in protection.
Price still acceptable la in RM 3~4~5K.
( but SG market price i not sure how much).
