I have such a script with 700.000 gals in database.
I can set-up:
- an XML-Feed to integrate in your site
- host your subdomain/domain with your design
- iframe or frame with results in the style of your site
It's FREE!
I'll even pay you to use it
drop me a line with your ICQ to: defresto [at] gmail.com
and I'll send you an urls of websites using it
