Still using NIS. Time to move to NSBU?

Hello all,

It has been awhile! Hope all are doing well!

I have NSBU in my possession, but never made the actual switch to NSBU.

Is it mature enough now to use it? I value your opinions.

Where are the latest download links for both NIS and NS/NSBU?

Is there an uninstall tool for NS/NSBU and a uninstall and reinstall tool for NS/NSBU?

Please let me know. Many questions!

Thanks and cheers,

Flavio :)
