Loaded Commerce Community

I'm considering buying a template which includes the CRE Loaded. I will need to change all the items to my items, all the pics, and all the descriptions and prices, together with all the essential contact and payment details.

Do you folks have any sence as to the difficulty of such an undertaking, or how many hours one might allow to delete and re-insert maybe 20 items for sale. In other words have you found templets helpful or time saving?

Last, I see there are lots of OS commerce templets out there without the CRE Loaded, and as best I can tell OS still provides a pretty good adm. panel for making changes. (At least it appears to) Do you find that the CRE Loaded is a worthy enhancement, and if so why

Thanks from a newbie if you get a chance to reply!
