Encoder for DSC

[dark star]

I have bought a Nexus DSC and encoder kit from 365 astronomy. I bought the encoder kit for skywatcher dobsonians as I thought I could adapt this for use on my home made dobsonain. The azimuth encoder fits on the groundboard fine. However, the design of the altitude encoder has changed and now has a magnetic strip. I can see no way of fitting this to my dob. I have a full size altitude bearing-a half circle.

The simplest solution seems to be just to buy another encoder and fit it mysefl, I can make brackets etc.  I appear to need  '10000 steps quadrature  encoders ttl'-I presume an optical encoder? I would like to buy from the UK to avoid probable long delivery times from Australia. Can anyone advise me where to buy an encoder in the UK, preferably on that I can just plug the cabe for the nexus DSC in to? I have tried using google but so much information comes up that it is very confusing!

I am hoping that someone has bought such an encoder and can let me know the best place in the UK to get one.

I can't answer your specific question but unless you're worried about customs delays I wouldn't hesitate to order from Australia. I'm in the US and recently ordered a Nexus II and encoder kit from Astro Devices and shipping was very quick.
