My two bits input on this. Seems like we lost flow thru productivity at the cost of slightly more cube storage. The company i worked for at the time did a complete rework of the warehouse to allow counterbalance and reach units to access the racks. It was like a 30% increase in flow thru productivity. was really a modified crossdock operation to be fair. Yep we sold the swing reach units for about 35% of the cost of the units. Burtwok has some really good points in his discussion. Also the person who bought in to the sales pitch left the company to pursue "other intrests"
