What type of turntable should I use?

I have a Sota Star Sapphire which uses hanging suspension but I'm wondering if I need any suspension at all.

My listening room is part of my finished basement. I live on a block where there is very little traffic. It is not a through street. So I don't get trucks and other heavy vehicles rumbling past causing vibrations.

My stand is very solid. I cannot detect vibrations from the speakers when I hold my hand on the equipment rack shelves.

All of this stuff can be seen by clicking on "my system."

What all of this is leading up to is, do I need a turntable with suspension, AND is there an advantage to having an unsuspended turntable?
