I’m with Gary – OEM Tak cables are very expensive!
If you are not into soldering, a good place in Brisbane for one off cables made to order is:
Qld Connectors & Cables
Unit 2/10 Dorsey St
Milton, QLD, 4064
I suspect the cost should be between $40-60? I had an auto guider cable made for my Vixen SS2K approx 10 years ago and it cost me $27.00
Cheers
