Which Sugar version to install

[mhrosso]

Hello,
Iam new to Sugar and I want to use it for e-commerce.

I see that there is plenty of modules available, but none of them is compatible with Sugar version 6, at least I think that its like that, correct me if not..

So should I install new version 6 or to have more compatibility should I use older version?

Thanks fo help.

It depends on which module to install though,
I suggest version 5.x/
