I have one. They are great pets. They don't require much care, don't eat much and make no noise. I have mine in a ten gallon tank. For substrate, I took some peat, wet it and packed it down in the bottom of the tank. I cut a coconut in half, and then cut a door in it for the hide box. Keep a dish of shallow water. Throw one or two crickets a week. Keep the temps at room temp. Keep them in separate tanks. If you break that last rule, it doesn't really matter, the female will eat the male and you'll be back to one spider per cage anyway. That's about it. Just like any pet do some research online before you buy it.
