I'm pretty sure I didn't Gorilla the capper. It seemed to be the bell that bent out of shape, and I could be wrong, but I'm presuming that it's using thinner or softer metal than a better quality capper. The handles didn't snap or anything like that... it just doesn't bend the caps around the lip of the bottle. It is a red capper, but I'm not sure what brand - it came with a typical 'starter kit', as likely did that of the OP. I'm sure some are better than others, and it would probably be a great service to many new homebrewers to identify which brands are more likely to be reliable and which are best to avoid. It would probably also help those who own LHBSs to get feedback from the community on what cappers are better than others. Sure, on the one hand they want to offer "competitive" prices, but they probably are also well aware that junky equipment that falls apart during the first batch is not helping to entice new brewers to continue with the hobby. One of the main attractions for me when I first thought to homebrew was the idea that I'd be saving money. As much as that turned out to be a bit of a fallacy (for me at least it is until I brew many many batches in order to recover my outlay on equipment), I'd bet that when it comes to brewers, we're probably counting pennies a little more so than the average population. Not that it's our only reason, or even primary reason for brewing, but as much as I enjoy brewing, if it cost me more in the long run to brew than to buy what I consider "good" commercial beer, then I probably would stop.
I too was surprised by the LHBS owner's reaction, and if there was any local competition it would have put me right off frequenting his store. However, he's been very helpful in many other ways, and given that it's the only place I can do a pick-up at reasonable prices and avoid delivery fees, I thus far have little choice. So far his helpfulness has far outweighed that one "transgression", so I don't feel that I've been put over a barrel.
