Don't really know about that one... I know if you're serious about cultivating though you should go check out shroomery.org and you'll get all the info you need to grow there. It'll cost less than that to get going and you can choose what strains you wanna grow. I personally don't know how well that kit would work tho, plus it's a one time deal. If you wanted to grow again you'll need to buy supplies anyway...
Thanks guys. I've checked it all out and plan on trying out the PF-Tek. My only problem is that the grow kits claim to be clean where as using the pf-tek means that I as a beginner could get a lot of contaminated jars.
