Had a similar encounter this week with my main stealer, i wanted a new ignition module for my Vit, response being sure, no problem that will £311+vat.
After i regained the ability to speak, i did a google search and came across a 4x4 breaker called EQUICAR and bought a complete dizzy for £30 +postage.
I also noticed on there website they were breaking several GV's including petrol & diesel.
Give them a go it may save you a fortune.
