I have a bunch of the bottle drops out on location, they work for me but am aware that a lot of people don't like them.
Think I only still have 1 of the short gate 2145's, everything else has been updated to at least equivalent of 5591.
Vendingworks has advertised refer decks for these:

Price seems good, but not sure when/if they are ever available.
I bought a new deck years ago from Crane or whoever runs the show at Dixie now - brand new factory deck was about $900 delivered.
As a ham & egger vendor, these work for me because they are cheap and other vendors don't like em - I updated/replaced most of my equipment by grabbing these machines up as other vendors dump them - never had to buy tall pusher set ups for the 2145 because I would find a 5591 with a dead deck for like $200 and scavenge parts off that.
One of the reasons I like the bottle drops is how easy the are to move around - pallet jack fits right under them and they are narrow enough to get through most doorways, the beverage stackers that sit on the ground are annoying to move without help - I can move a bevmax solo but need help with a stacker.
