The vinyl tubing at Lowe's & Home Depot should be fine, but I don't use any vinyl tubing any more. It curls and has a memory and is a pain when cold. I moved to silicone tubing from Austin Home Brew. Info Here
It cleans easy with a soak in Oxiclean and sanitizes with starsan. When you are ready to use it to rack, it hangs down without touching everything in sight like a curly vinyl hose. It costs more, but is well worth it. It's also high temp, so you can use it to move hot wort from your mash tun or kettle.
