It sounds like you want to get a whole body vibration platform that is less expensive than the Marodyne. Please do be careful if you purchase a less expensive one because it could be harmful, as Keith McCormick mentions in the pages from his "Great Bones" book that you posted 6 days ago in this thread.
At one point I thought of getting a Marodyne but balked at its price (among other concerns). I haven't thought of purchasing it since reading the vibration platform section in "Great Bones" back in January. Like Dr. McCormick, my views on the vibration platforms are still evolving. I look forward to reading the results from the VIBMOR randomized controlled trial, which I think might be published by spring 2024 (see https://trialsjournal.biomedcentral.com/articles/10.1186/s13063-021-05911-4). I feel fortunate I am in good enough health to regularly do weight-bearing exercise and strength training.
