can't help you with rack choice
My beautiful rack had legs that were recessed from the front and back a bit.
Thus weight was in front of a fulcrum point, and weight behind a fulcrum point. I made new strong and strongly attached end supports that extended behind and in front a few inches. Made a big difference.
It's a beauty, rubber isolators for two glass shelves and glass top.
Because my floor is so springy, I needed one more solution to get a step away from the TT after I dropped the needle in the run-in groove.
wrapped them in black tape, did the trick.
