I second the recommendation for Bumper Crop. They also carry (and keep in stock) some things for Mag drives that a typical LFS might have to special order. For example, replacement impellers and replacement impeller housings. At the beginning of the year, one of my Mag 7's that is about 7 years old had its plastic cup that holds the impeller in place snap off. $10 or $15 later, a new impeller housing, and it's like having a new pump again. I love Mag drives! Awesome little workhorses. Pisces was going to take 2 or 3 weeks to order a replacement in, but Bumper Crop had it in stock.

I'm not sure that Bumper Crop's price on new pumps is better than MO, so, it does pay to shop around a bit. They're definitely in the ballpark but anytime you have retail it's going to be hard to compete with MO because of the necessary overhead and stuff. But basically for miscellaneous bits and stuff like that, definitely worth a visit there once in a while. I once got these little 1/4" bulkheads there (for some kind of irrigation drip system). But awesome stuff, I just drilled a hole for my topoff and don't have to worry about sealant or tapping or anything like that.
