376159 Web Site Transfer

I have 3 sites and am having issues with all 3 shopping carts. The shoppings are a run off of oscommerce/CRE. I would like to see if it possiable to change shopping carts. I would perfer a shopping cart that is user friendly, CRE the real one would be fine. I would like any and all ideas, these 2 sites are down and can't start any SEO/SEM until there fixed. Sites are [login to view URL] [login to view URL] [login to view URL] I'm told this is a fairly quick job for the experienced person. The newadulttoyscheap, has logo design but the banner is just ok, if you have a banner idea that would go with the logo design let me know. vibrationdomination is a copy from the above site just with different products and drop shipper. This one needs its generic banner and logo, if price is to much I will park this for the time being. swingingwoodsand9holes, this site has the logo and banner in place, all products have been added, but images need to be added to the new shopping cart.
