How much did it cost you per rack?
Chipco tray cost is $2.25 per, plus shipping.
I'd like to know how much wiggle room you have as well. I ordered 66.7mm racks from Straight Poker Supplies in the past and I could fit 21 non-mint Paulsons in them.
I compared four types of stacks - completely minty
BCC MGK's, Stardust cash, very lightly used Casino de Ithmus, Milanos, and casino-used Par-a-dice. The Par-A-Dice fit snugly 21/barrell. Milanos fit 19-20/barrel (hooray
CC quality control!) as expected. Stardust and Casino de Ithmus 20-stacks fit basically the same...definitely *some* wiggle, and maybe even enough room for a spacer, but certainly tighter than the no-name racks. The
BCC's fit the best overall, but still had some slight wiggle.
I was expecting a much more snug fit on the Paulson's for some reason, and to that end I was disappointed, because snug they are not. Better than the off-brands, mind you, but once you include shipping costs (which were somewhat significant for me), I'd sooner go with the cheaper racks if basing on barrel fit alone. I had little more ease stacking the racks in a 600-carrier than I did the no-name racks. That being said, the quality of construction on these racks alone is worth the price of admission. Almost twice the acrylic thickness throughout the mold vs. the no name racks. They can definitely take more punishment than the cheapo stuff, and that extra sturdiness/longevity makes them easily worth the price paid.
In short, if you just need racks to carry chips in from table to table, cheap ones will probably be fine. If you need racks to stack in 600 carriers, the Chipco ones aren't much better than the cheap ones depending on how worn your chips are. If you tend to be harder on your racks, though, or your discerning tastes appreciate a tighter fit, however slight, then these are definitely the racks for you.
