Lovely things people have said, and what we should do about them

So, we're far from perfect eBay wise, and we make the odd mistake, but I do worry about the quality of other traders' services on eBay. Today we had an email from a customer who said (and I kid you not) "You offer an excellent service, and make online buying a pleasure
Other traders could certainly take a leaf from your book." Now - that to me sounds like one of them quotes you see on posters on buses which say "They made learning to drive fun and easy - JM, Solihull." I'd like to put some of our quotes on a website or something, but it seems a tad on the cheesy side! Should we put some quotes in our ads? What do you think? Comments welcomed...
