Well, some people never learn do they??!! Having been patient in putting together the parts list I'm now left to nurse my pride and temper my over excitement. The cost for the bits I can't do is prohibitive. I've got to kill the project and try to recover what I can from parts that can be returned and refunded, and the rest are at the mercy of the Marketplace/ eBay.
Sad, but I can't sink £500+ into this.
