Why would people be put off buying something because of a change of personnel, unless, of course it was the person who started / developed / ran the business and it was not going to function without that persons presence.
Never had any dealings with Dave Ingram, I always thought he was a carpet cleaner, who was knowledgable and helpfull in technical matters.
Only dealt with the company concerned, on two occasions, following positive posts on here and was happy in those dealings.
