I want to get into e-commerce. I plan on purchasing either an OsCommerce or a Zen-Cart template and using one of these services but I don't know which one to choose.

My number one priority is ease of use since I have zero background in any of this. The next best thing would be whichever service comes with the most easy-to-understand for a novice instruction manual, written in English, not computer-ese. I am willing to learn, as long as the instruction is not way over my head and written for folks with website development degrees.

One more question I have is what this means (it is required for use of the template): Hosting with PHP4x and MySQL4x; Apache only (on Unix/Freebsd/Linux/Windows); runs on most server specific configurations ranging from dedicated servers to shared servers that utilize different PHP configurations such as register_globals (should be ON) and safe_mode restrictions I have no clue what they're talking about and I hope someone can translate that to English please. The hosting has nothing to do with my PC, right - it means an online service I choose to host the site? What is MySQL4x and what is Apache? And what about server? Is that something on my end or my hosting service's end?

Thanks a lot for the help!
