For the shocks, KYB Gas is what was fitted in our Cefiro Elite before...

For the stab link, i'd go with OEM. Shouldnt be too expensive. Try checking the CASA price and with JAISI as mentioned. In Pasay there's Advance along Taft (Was this the shop you checked out?). On Youngbros, the prices of their OEM isnt too far off or is actually similar to the CASA price.
