you can get a PC cheap on craigslist, ebay or a second hand shop.  I spent $20 on my gigantic one...  and you don't even really NEED a PC for PF, you can fractional sterilize the jars, you just have to be more on your game about it.

Early on I tried a couple of kits and found that the genetics in the spores that they provided to be very poor.  I ate a TON of fungus and got barely a body load.  I did my own PF and grew Golden Teachers and had a much better experience.

Just my $0.02...
