I finally came across a Mass Storage System on Facebook Marketplace. Dan Powell in Englewood is offering this 43" tall x 70" wide system for $500. Retail is $436.06 (with Kettlebell Tray) and $115.75 for shipping and $23.47 for tax, the magic number is $572.28. $500 represents 87% of delivered price and 115% of retail.
If it was my perfect configuration, I might grab it for 100% of retail.
I would like a 75" tall x 43" wide, but am also debating a 43" tall x 43" wide. The smaller one would make more sense in my current space. The larger one would make more sense in a larger gym. I cannot imagine ever getting a 70" wide system.
