> You can buy the oil and bake your own, but that requires more money and effort up front ($50-$100)

It doesn't require much money or effort at all. I regularly make small batches of oil using as little as 0.5g of kief.

I melt a little coconut oil, dump in the kief (would work with weed too, of course) and cover with tinfoil. Then I bake it at 115C/240F for 27 minutes - cannaoil, done!

THC is metabolised into a stronger form, THC-9-COOH, so edibles really make it go further. Plus the effects last several hours instead of the 1-2 when smoking or vaping.

> Vaping using concentrate is likewise not cheap.

Erm.. you don't have to use concentrates.
