Work fine, just remember to click "no" if the J-Link software offers to upgrade the firmware.

Well, that is an affordable one indeed!!! If I find no one else, I'll purchase that one!

McBryce:
Yup (I assume you meant to quote my post?). I've been using it quite a bit since I bought it about 2 years ago and it's never given problems yet.

Yes I meant to quote your post! :p

That's good news...

And is there any way of knowing how much time these devices takes to perform the memory dump?

McBryce:
It's been a while since I dumped the memory from my MSO1104Z-S, but I think it took about 6 minutes. I used the "Speed 6000" command first of course, otherwise it uses some snail-paced default that takes forever.

Here's a post where someone else used exactly the same method, with full instructions on what to do: https://www.eevblog.com/forum/testgear/sniffing-the-rigol's-internal-i2c-bus/msg599846/#msg599846

Nice... I'm going to order one of those and when I get it, I'll ask for help here if I need!
Also need to save these links that will be of great help when I'm about to perform the memory dump!
