$30 in gas? You might as well pay $5 more for shipping and get one from LiveAquaria that has been quarantined and comes with a 2 week guarantee. The slight difference in pricing makes a world's difference in quality. What's the point in saving a few bucks for a fish that might die? Then you're short $100 some dollars just because of the slight difference in pricing. If anything happened to the BSJ if you purchased from LiveAquaria, you can bet that they'd do something about it. I've had only great experiences with them and that's the only place I'm going to try a BSJ again after a failed attempt from getting one at my LFS. Reading articles, Kevin of LiveAquaria said that it wasn't the temperature that was the biggest issue. Rather, it's how BSJ are handled when caught and shipped. They're very susceptible to disease and stress during those phases, and LiveAquaria would have to go through all those troubles in the beginning so the chances of it being a good specimen is greatly increased if you buy through LiveAquaria.
But in the end, it's up to your choice. I'm just waiting to see what else I can get from LiveAquaria to get free shipping, hehe.
