Lots of good info here. Just thought I would mention that the JTH-7 is a discontinued item, which is why you can't find it in stores. Even so, it's only around 3-4K BTU output.
OLW is almost right, 1095 is hypereutectoid, not hypo. Specifics aside, it's not easy to get a good HT in any forge using 1095. Best to stick to 1084, it's super easy to HT, very inexpensive, and makes a great knife. I know the fancier steels are tempting, but save your money and spend it on other tools than fancy steel when just beginning.
