After reading thread after thread of people having problems with their conversions it makes me feel much better about the price I paid while doing mine. No problems were had other than my own stupid mistakes and when wired up started first time

I know this is no help to anyone I'm just making myself feel better about having no money left

As Brad says doing things cheaply will lead to problems you want to get your parts from trusted sellers and work done by people who have a reputation for knowing what they are doing
a £2000 conversion imo will be shoddy at best
