So I finally cleared out a space in my garage and I decided I want to put a speed bag up.

I dont really want to spend over $400 on one..so here are the choices.

Please let me know what platform you think would be best/least vibration and/or any other recommendations.

(this one is 500 but if you guys think there with a substantial difference between this and say the $400 one, I might as well just spend the extra 100)

Thanks for any help in advance
