Most people tend to go with Wallingford, and it was this that caused me to order some stuff from them as well, namely tubus racks and ortlieb panniers. Communication was great and was very happy with the panniers. But the second time round when I went to order the racks I received no communication back to a question about racks being out of stock, a month later I finally got a reply to say the dude who I emailed had been fired cos he was so slack, and that they actually had them in stock for quite some time but the web site had not been updated. The lady who replied was sincere in her apology, so I went ahead and ordered them, but then I didnt hear anything back for another month when I emailed to get a quote for shipping overseas !
So finaly about 2 and a half months later I got the racks, am very happy with them, but it was a little bit hit and miss for me from wallingford.
