Agree with David. Pictures bring out ideas, else serve as reminders to those who might have worked it before.

Anyhow, if you decide on the original MKs, I've definitely seen them in Singapore Hobby Supplies. But the last I remember the stock dwindling.

Strangely enough, I've seen them at another hobby store in Singapore too - Rotor. Both of which are on the web.

Good luck. You've just tempted me to take a trip to Singapore Hobby to see if the MK Joker 60 is still there.
