New rack or power conditioner


Hello, new to this forum. I am a long time looker however. I am in the market to up grade my rack, which is a 15 yr. old home built 1 1/2" mdf shelves and 3/4" allthread supports, and a Tice power conditioner. I only have funds for one item and was woundering what is the most important, the rack or power cond.

Thanks for the input.

Well I decided to go with the Stillpoint Ultra Mini footers and build a new rack.
Thanks for all the help.
For the money- without doubt a power conditioner. You can experiment with improvements to your rack when you can hear what your present system can really do.
Woodworker501, very curious what your thoughts are using the Ultra Minis? I am thinking about buying some to try out as well.
