On large ecommerce sites, I find that I really like faceted navigation structures that help me zero in on the product I want using the descriptive data I choose: brand, price range, size, color, etc.
I'd like to implement a similar navigation structure on a site I work with. We have all the specification data we need, but we are really struggling with the interface. The handful of solutions our programming team have turned out just don't cut it. We've looked at purchasing some software, but everything I've found is enterprise level starting in the high 5-figures and going up quickly from there.
Isn't there a lower cost solution out there for smaller ecommerce sites? Is this technology so complex that it is only available to the upper echelons of the web?
