Update:

Option 1 - Lumenition System (about £400 including Dizzy)
Option 2 - Aldon Ignitor II with Coil (about £450)
Option 3 - 123 Distributor (£399)
Option 4 - H&H Complete dizzy, with in house electronics mapped to my engine spec, including electronic coil (£215)

Arwyn and SimonH have also both recommended the H&H so we may have a winner......
