Aries owner, what isolation device do you use?

Since my house has crawl space, any turntables without suspension will sound muddy if they just sit on my rack. Dealer suggested putting a slab under the Aries, Music Direct also sells Black Diamond Racing kits specifically for Aries. What other options do I have short of mounting a wall rack which is not an option for me? Or will I be better of selling the Aries and buy a table with suspension like Oracle?
