On my Scout, I have conquered all of the problems you have cited. Target wall mount, spring suspension Brightstar Audio platform, Solid brass spikes on table and motor, cutaway portion of lid supporting motor, Mapleshade NanoMount System drains vibration away from cartridge into arm, and also directs it into the plinth, where it goes into the sand box. A 300 RPM motor and PS Audio P 300 Power Plant steadies the voltage to the motor.
A TTW copper mat and heavy brass clamp securely holds the lp to the Mapleshade Integrated Record Coupling System. Arm is the JMW Signature. Dyna XX2MKII gets everything that is possible out of the grooves for this cartridge. How does it sound? Unlike most any Scout you are likely to encounter, that is, amazing. Credit also goes to the MintLP Tractor, all the upgrades would count for nothing without its contribution.
I know from my experience that the Scout can give you far more than you are currently getting from it. It has come a very, very, long way without dropping thousands into $1200 plinths, $1000 controllers, and $4500 arms.
Hope this helps. It surely helped me.
Best regards,
Dan
