Anyone have any cheap comments regarding any power bar or surge protector
that have the best RFI EMI noice filtering?


A power bar isn't going to help much:

As others have suggested, find the source of the noise, and then think
about solutions. In my house, it's the multitude of wall warts and
switching power supplies that generates the bulk of the noise. These
switchers turn off when not charging or powering anything. So, no
noise when they're plugged in, but not being used. Consider using
clamp-on split ferrite filters if you suspect that the noise is being
conducted down the power line.

Although the article is on audio noise suppression, it applies equally
well to RF noise suppression.
