I bought mine from them and have been happy.
I also bought the Hatchery Disk -

Pour salt water in, sprinkle eggs around the outer chamber, and leave it for 24 hours... no electricity, pumps, or light bulbs needed. It's awesome. The yield isn't as high as when I set up a regular hatchery with bulbs and pumps and everything... but it requires zero effort to produce a fairly decent yield.
