The topic of PCB manufacture attracts spammers like flies. So a new poster whose first post is to promote a web site is 90% likely to be a spammer (e.g. Bruno65). He will probably come back later and edit in the URL.
The OP is very likely a spammer as well, a new user signed up to ask a generalized question about a highly spammed topic. They do this to create the impression of innocent inquiry and sock puppets came in later to do the spamming.
Spammers don't care about any discussion, they do it increase the page rank in search engines.
Unfortunately that means threads like these tend to be very poor quality, with 50% of the posters spammers or sock puppets, and almost impossible to tell genuine testimonials from fake ones, unless you are a long time user familiar with the people here.
