Unfortunately, any of these programs you're looking at are going to be a cookie-cutter, and what you can do with it will be limited. IMHO, you will ALWAYS be better off with something more customized to your needs.

I don't know if it's against the forum rules to say this, and if so I apologize in advance. But as a web designer, I've created custom websites that the owner can completely manage themselves for less than $2000, including a shopping cart and catalog program.

Please know that I'm giving that price as a point of reference, not as a solicitation or anything like that.
