Well I have not yet had the opportunity to compare it with any other ecommerce packages yet. It seems to work really well and is easy to set up, although I found the template/skinning system a bit confusing.
However saying that, since setting this up (which is in effect a free template I found and modified) I have started to get my head around the way cubecart templates work.
I will say that it is a bit basic out of the box, and there doesnt seems to be a very big resource of free mods and skins. I gather if your prepared to spend some cash then you could unlock its possibilities.
After Ive finished the
website hosting Im going to have a look at oscommerce as that looks quite good and there seems to be a much better community for things like support, free mods and skins. If your after a basic ecommerce package however then I cant really fault it, but Ive not explored the alternatives yet as I said.
