Best shopping cart ?

[joyboy2001]

Hi,

I know this is off topic, but I want to install a shopping cart on my website. I have never installed one before and I guess it will be just as difficult(if not more) as it was while I was testing out various forums and came to the conclusion that SMF is the best !! This, however, will be more difficult because I has experience with forums but still have none with shopping carts.

I need to know which cart is the best in terms of (in no particular order) :

1. Ease of use (Admin)
2. Ease of use (Customer)
3. Support staff
4. Ease of initial configuration
5. Ease of upgradation
6. Ease of troubleshooting
7. Etc ...

Please suggest the best cart and please also provide the reasons for doing so ...

Thanks
