Doing the transition from Acajoom to jNews was something I never did, so I gave a swing at Joobi online support.
There's only one word that comes to mind : "AMAZING!"
I had loads of questions & got Immediate replies, pertinent information & most of all a very kind, patient and understanding person to chat with.
The Component itself is very straightforward & well layed out and although I haven't sent a newsletter out yet, I'm sure that it will work even better than acajoom (which worked perfectly) and if I have any kind of problem, I now KNOW that I'll get immediate support & fix.
This Live support is unbeatable.
I highly recommend choosing the Joobi team. It's worth lot's more than what they're asking.

BEWARE, when embedding your media, DO NOT put the file extension (i.e. .flv, .mp3 etc...) the plugin puts it in there for you!
This works, out of the box, under Firefox AND IE (unfortunately can't say the same for others) and I highly recommend it !
