A business might gladly suffer a small loss providing a service if the alternative of not offering the service might be to incur a much larger loss - for example if it takes engineering time away from other projects.
Of course there's no compulsion - the option is to go elsewhere (get a quote from your local TV shop who have little experience? Around here UKP65 before they'll look at it.) or get it done for free from CTL.
We're simply acting to isolate Simtec from spending all day on the phone bartering with angry people who think that because CTL recommended Simtec that they should work for free and A6 should pay for the resultant lost engineering time - but in the meantime we offer people an alternative option to Framlingham.
