Simple shopping cart...

[Jonathan Smith]

I'm looking for some sort of shopping cart software for some of our 
webhosting customers to use.  It needs to be:

Reasonalby simple to setup/configure/use (I don't want to spend hours 
on each install)
Some sort of product list - either a plain text file or 
mySQL/PostgreSQL based
Low cost/open source/free.

I've looked at PHPshop and commerce.cgi - PHPshop looks possible.  It 
will require a significant amount of time ti setup, but after that it 
won't be too hard to setup for each user.

commerce.cgi looks like a major pain - I'm starting to hate perl-based 
CGI scripts.  Unfortunately I've inherited the web server and I really 
can't make major changes to it's setup - at the the moment there's 1 
cgi-bin directory that holds all the cgi scripts.  commerce.cgi seems 
to be happier in an environment where every virtual host has it's own 
scripts.

Anybody have an suggestions?
