Are you using the two piece clamp, with the frosted coaster, and little black delrin knob? It works, but is a bit more of an inconvenience due to two parts.
VPi's entry level all delrin clamp is good, and should be within your budget. Next one up is their Stainless Steel knobed clamp.
Weights, such as TT weights, or their clamps don't give as much adjustability, nor IMO do they work with VPI's system, with Rubber Spindle Washer.
Since records vary in a degree of warpage, or dishing, the VPI Clamp system , with the cupped underside of clamp, and spindle washer is pretty tough to beat. Cannot figure out why TT Weights never made an exact clone of the VPI Clamp, with dished underside. It was one reason I never bought one of their clamps. Harry W's clamping system is/was IMO very ingenious.
I can remember years ago, the claims of how this clamp, or that clamp miraculously improved my sound, etc, but any differences between clamps are usually very minor-small.
A better Platter, yes, big changes in sound, but very little with the various clamps. It's more a matter of aesthetics, and cosmetics.
Proper coupling to the platter is IMO important though. I'm sure others will agree, that a record, even slightly see-sawing up and down can be heard. Mark
