Ignitech Tci Non Progammable Ignition Unit - Where To Buy?

I'm told this is the unit of choice for the carby to replace standard units (especially if you are using Dynatek coils). Anyone know anywhere in UK you can get them?

Thanks all

 

thanks chaps, for some reason it never occured to me and I frequently buy from Europe and USA.

 

Just to close this off, Ignitech were a pleasure to deal with and the unit is with DHL already.
