Why is it no one really has nice templates for ZC but the other ecommerce packages have templates coming out the backside of the elephant? ;)
Well, these other carts don't have FREE templates coming out the backside.
I've looked at other carts, and again recently. Actually have Prestashop, Opencart and CS-Cart loaded...or ready to be loaded...on some test sites. All have their pluses and minuses. And IMO, Zencart can compete with all of them.
Templates: I think that none of these carts have the selection of FREE templates as does Zencart. But then Zencart is, insofar as I can tell, more pure open source oriented, primarily catering to open source templates and contributions and less hospitable, if that's the word, to commercial endeavors. Whereas the other "open source" carts seem to have more of a commercial industry revolving around them. And in the case of CS-Cart (like Magento) even has it's commercial upgraded cart. (Which I suppose the Zencart team could do, if had such a mind.)
Opencart: IMO has the best commercial templates at reasonable cost. You can get a very nice template for $30 or so. I've been tempted with Opencart just because of this, since as I said, templates have also been my main concern. But there are other things that Zencart still does better that we need: like Easypopulate (the import function of other carts looks much more complicated.) And Zencart free templates are coming on strong, now. Otherwise, if you go TM route, the templates from one cart platform to another look pretty much the same: usually very nice and about the same price.
Prestashop: The new beta 1.5 changed it's admin, now using drop down admin menus. But it is a pain just doing option Colors and Sizes. And seems to me a little buggy, even the "stable" version.
CS-Cart: Probably the most impressive, to my eye, with a nice new default template. But the "free community" version has alot of functionality turned off pending upgrade to a commercial version. Main con people talk about is that the cart is supposedly slow and really needs a high-end server, kind of like Magento. Here's my CS-Cart I've been testing as time permits:
http://prom-mart.com/demo-cs-cart/
Very nice. But, looking at the product pages and such, isn't doing anything that Zencart cannot, especially if grab mods such as the Tabbed Products Pro for the product pages.
I've noticed that Zencart's version (plugins) of things like Image Handler, Easypopulate, CEON SEO Rewriter seem more advanced than these other carts. So I'm convinced that Zencart can compete with these carts on functionality...and templates: free or commercial
