Thanks for adding to the thread.
Many people won't use sand because they think it doesn't hold much moisture. A good way of understanding how much moisture it holds would be to weigh a pot of dry sand and then weigh it wet.

Anything that has Horticultural in it's name is probably going to be expensive.

The most important thing to keep in mind when choosing a grain size range is that the smallest grain size in the range determines the aeration not the largest. Kinda like a chain where the weakest link determines it's overall strength.
That's the main reason why I wouldn't recommend any of the concrete sands, they have a large grain size range. Screening concrete sand would work if it contains enough of the desired size.
