One thing to note about the cost of Pro mix, is that if you solarize it or sterilize it otherwise like in trays in very low oven, you can use it year after year after year after year. So you're only spending the once, plus a little bit to replenish the supply every year.
I guess another thing would be that since it comes in a very compressed Bale, it fluffs up to twice its size, so it's really not any more expensive than something like Lambert's or horrible awful yucky Miracle-Gro
And as to Mark's comment about mycorrhizae, you can buy that very cheaply online and just dip your plants into a bucket euth it mixed in before you put them into the Pro mix. And a little of that goes a long long ways, especially since they are live colonies and they will reproduce into the quantity that's needed once they're in the potting mix.
