Hi 69tri1, the shopping cart on my site will be up and running in a couple of weeks. The cost of just raising the rev limit will be £30 +VAT and the cost of a remap and raising the rev limit will be £85 +VAT, of course if you're outside the EU the VAT won't worry you. There will also be a return postage charge of between £8-£15 depending on where you are, this is a signed for service with insurance.
I can understand your concern as the igniters are very expensive, but the process is just a connection to my laptop, make the required changes and return in the post. I have worked on many 360° igniters with no ill effects and the process is identical.
