Yes the mushroom kits will work.
You could also just replicate a kit and buy all the supplies from wal-mart and home depot.
If you want a 100% working product, because it can sometimes be frustrating creating your own glovebox and fruiting chamber (plastic cracks like a motherfucker), then I would recommend
mushbox.
They have all the supplies to grow mushrooms besides the spores, and they also have good prices.
Here is a kit that comes with everything you need to grow mushrooms (besides spores), it even comes with 12 pre sterilized BRF jars (the jars are re-usable, too).

If you decide to go with that kit, while not necessarily needed for growing mushrooms, its definitely worth it to make a glovebox.
My glovebox is just a clear sterlite tub with 2 four inch holes in the side (about shoulder width apart), with 4 inch PVC couplings (with threading) and 4 inch PVC plugs.
A glovebox is a draft-free sterile environment to innoculate your jars in.
And to get spores, there are 2 reliable vendors that I recommend, they are
Sporeworks and
Spores101.
Spores101 is billed in canada (so you cant use pre-paid visas, unless they allow international orders).
Sporeworks is billed in the US so you can actually use a pre-paid visa.
