I tried your site couple weeks ago, and AllPCB came up on top for all results (such as 3/4mil trace width etc. etc.) even though they don't offer it.
Yeah. On Nov. 29th, I changed the code for ALLPCB to fix the trace width, drill, and board thickness options.
What happened was, ALLPCB used to offer more options, and I coded PCBShopper that way. Then, ALLPCB cut the number of options on their form (without telling me, natch), but their back-end code that calculates price didn't change. PCBShopper works by submitting queries to that back-end code.
The best solution would be for PCBShopper to get the web form and parse the HTML to see what all the options are. That would be a real PITA though. Maybe what I should do is just check every day for changes in the form. At least then, I'd be alerted when they change their options.
Yeah, I think I'll do that.
