If price is a real issue, there is always obscure stuff floating around on Ebay. Recently I have seen old Oriental G3, Dupont Velour Black, Luminos Bromide, Luminos Charcoal.
The upshot is price and old foggy papers don't matter so much for lith. The downside is, if you find a box of magic, you will run out of stock by the time you are really having fun. And you will never see the stuff again! (Better to love and to have lost than blah, blah).
But if you are learning lith, certainly the Fomatone MG classic is the fastest way to good results, and with toners, great results.
