I had the old eyelet setter and a hammer for a long time. Crop-a-diles weren't available where I lived. But when a kind person in the US said that they were on sale there for some stupid amount and did anyone want one, I jumped at it. The cost of it including shipping was half what I could order it for anywhere else, so this dear lady sent me one and I never looked back. No more finishing touches having to wait till the morning 'cos it's too late to start hammering.
Oh and one more thing, if you get a Crop-a-dile you will spend the first few weeks looking around for random things to punch holes in, just to see whether it will. I did. Actually I still do.
Eyelets are for decorating - for giving the page personality.
I have the Crop-O-Dile Big bite and I keep it in an 12 x 12 art bins case. Then I went to one of the big box store and bought the bead cases in the jewelry department - the rectangular boxes with round containers in them. I use those for different color eyelets, brads and quicklets. The rectangular boxes go right in the 12 x 12 with the Cropodile and it goes right in my crop wagon for crops. Just stays in the crop wagon even at home in my scrap room.
Love my Karen Foster Clikit tool. Everything in one handy little box. Not sure if they still make them anymore though... had it for a long time.
My favorite too. I have a Big Bite, a Croc-a-Dile, the hammer etc and the Karen Foster is my fav. I don't even keep it in the box anymore: all of the setters are in a baggie and the clik-it and baggie sit in a pocket of my tool bag.
