Ambrosia,
Quantum Particle, and
Ankou's Strand of White Hair might be good idea, you'll most likely need them later if you're planning to craft Backwings, they'll probably be cheaper as well, though be aware you will fail a lot.
Hermes' Moon is pretty much the easiest, though because inflation, you won't make any profit, though you can use the Alchemized ones for Mercury's Moon.
Yama no Tamago isn't so bad, if you can great the Crystal Tree of Cyndor at a nice price.
Archangel's Blade might break even, depending on how you acquire the items it needs.
Helmet of the Great War is simple and has nice resell value, and used for Formula 8: Coat of the Great War, though it'll need 5 of them.
Flossy Fox is fairly easy, might turn a small profit or break even.
Grace Meow doesn't require much, and can turn a profit if you can get the Formula.
