What eCommerce program are you using?

Hey guys I'm trying to set up a shopping cart on my website and I'm wanting to know what eCommerce program you are using?

I've been told to go with OSCommerce.

OsCommerce is ok they have issues when your trying to sell items such as t shirts were you have different sizes and a price change for larger sizes. You can also try Joomla http://www.joomla.org With a eCommerce add on http://extensions.joomla.org/index.php?option=com_mtree&task=listcats&cat_id=1824&Itemid=35 You could also use Joomla for your whole site so there is a seamless feel when your navigating from your web site to your shopping cart.

zen cart

Build your own , OsCommerce is alright but they have had horrible security flaws in the past, especially with add ons. Zen Cart is a much better solution, and is actively being developed by good programmers., it's also what we use at work to build for clients.

I would keep an eye out for Magneto though, it is still too early for use imho, but it has great promise.

Depending on your abilities, if your a great php5 programmer, I would use Magneto, but if your looking for a prebuilt, I would use ZenCart.
