Electronic ignition.

Just to give me something to do, I've decided to fit an electronic ignition to my 74 TX. I had a Boyer on a Triumph Bonny I had back,in the 90, it worked well, was easy to set up and time and I never had any problems. But this time I thought I'd trY a Trispark. Trispark are at Blackwood a suburb in Adellaide, just up the road from Aldinga Beach where I live. I thought I could drop into their shop and pick one up, no such luck, they have no shopfront, only online sales. So, really no point in fitting an unknown, I can get a Boyer for around the same money, also online.
Does anyone have a trispark for a review?
If I decide on a Boyer, apparently they don't supply a coil, will a CB750 coil work with the Boyer? I have both types, the one with the screw on HT leads and the one with the fixed leads.

Have a look at their website. They make 2 types red box and blue box. Decide what type of type you want then look up the coil specs.http://www.boyerbransden.com/coils_ballast_resistors_plug.html
There are some review threads on here about the Trispark.

Need to be careful there
I remember Boyer warning for having power on for long duration ..kicking or forget it on
Risking to fry the Coil.
And there are warnings frying the Box Also
Looks as they have different coils for Honda 4 s and XS 650

I always thought the Trispark was a cut above the Boyer system in the quality stakes? A good reputation on British parallel twins.

There seems to be a price disparity betweenthe US and Aust: The Trispark. Is $448 in Oz including GST and postage., whereas the Boyer Bransden is $470 all up.
