I can't say enough good things about Esvon and their classified ad software. I've been working with them for almost three years and I'm on my third site. Their technical support and response times are fantastic and I've used them for all of the core/Db mods and enhancements that I've made. I couldn't image writing this code from scratch or using some other vendors package. BTW the first Esvon site I launched recently sold for a mid 6 figure (US$) amount.
