Do any ones work better than others? I need to get one to put my Prolines in when they arrive. I want to make my life easier so i figured I'd chase the one that is easiet to load . The Personna one seems pretty easy, push down and insert, and it will hold 20. It still has 17 in it, so I was thinking of doing 1 at a time for now. I saw some on eBay, but people want stupid money for them because they are all "vintage". Thanks for the input gents!
