Ya, that's the frustrating part right now, everyone you look at is selling stuff from level 1 mobs. Unfortunately right now, things are generally priced at what you're willing to pay for them. I paid 65k for a chocobotail saw, overpriced? Probably, ingredients hardly cost that, but, just to get it done, it involved about 3 people. So after the 3 split the costs of it, they make about 21k each, which isn't that great. To me the price was right, I actually started succeeding my level 15 leve quests, and gained a few levels in carpentry.
As for other items that are being mass produced, just do a bit of research online to see what it should be worth. I geared my Archer and my Carpenter (with crafting) gear for very cheap since everyone and their mother is leveling weaving.
The biggest issue right now is EVERYONE is leveling a craft, only those who get way ahead will manage to make any profit right now. But I do agree seeing 20 willow and Lauan Masks for 10k a pop is ridiculous seeing how it requires very little to make them. Once the game's been out for a couple months, we should see things start to settle. Even if they add an AH at this point, all you'll see about 1000 sets of every low level item.
