I would wait. You can always ask your lfs to order one for you when you are ready for it. They tend to grow quickly when you first get them...
They are a long-lived species as well, so plan on a long relationship with it.
The salt depends a little on the species. They have highly sensitive skin, more so than most scaleless species, so adding salt to the water (or any medications not rated for scaleless) will cause their skin to crack and peel, like it is severely chapped. (Found this out the hard way)
Also, the lfs might not tell you this, but they won't readily accept flake foods, and they're bad about waiting around for a while before they eat. Bad news if you have really aggressive eaters in the tank with it.
Whenever you do get one, be sure to have the lfs clerk feed it in front of you. If it doesn't eat, don't buy it....also, make sure it's little belly isn't caved in. These are both signs of starvation (a common problem associated with breeds that don't eat normal flake foods).
