Thanks for the contact. Was looking for him.
The last number I had of P.K. Chan is:
Yip Chieng Trading Services
17A Jalan Selamat
Singapore 418538
Tel: +65 6441 9560
HP:+65 9691 2577.
I think you can arrange to visit his office to see a wider selection if you are unsure of which model you want. On the other hand, if you are very sure, just tell him the model and the color you need, and he will drive down to meet you at your place of preference. He is a nice chap. He also sells Quantum flashes too.
Don't blame me if this is the wrong number
