If you speak to 'The Tuning Works' he mainly focusses on the popular 250's but he is a Zeeltronic dealer. My CDI was around £250 I think
Another nod towards Zeeltronic, Ive dealt with Sean from the tuning works who is the importer and Borut who is the brains behind zeeltronic many times. If you email Borut direct and ask him what unit is best suited to your application I'm sure he will be able to provide you what you need.
