what about this? Not exactly peat moss, but sphagnum will eventually decompose into peat, and I think a lot of people use different combinations of peat/long fiber sphagnum, silica sand, and perlite.
You can also find perlite here and vermiculite here - I would ask around about Vermiculite though. Some consider it risky because of a few added minerals. I am currently using a 50-50 mix of peat/vermiculite with a topping of LFS in my VFT. I had a couple road bumps, but things seem okay so far (almost 1 month in)
