The experience I have had with cappers is they're pretty much all the same, although I tend to use a bench capper if I have a choice. The hand cappers and old age tend to have a disagreeable effect on the bottles, ie. they shoot out from under on to the floor. Of couse, that's just me. The only one I'll never use again I call a "slap capper" It looks like a blackjack, and the idea is to position everything and tap it with a light hammer (wrench, socket, rock) and the whole mess is capped. They tend to break bottle necks, or chip them. Bottom line, the cappers I've used are all the same size it seems, just use the one you like.
No, I like snow, it's the shoveling it I could do without....
