Nice. Inscription is a fun profession too. The last few points aren't that bad, and you feel like you are genearlly making useful items all the way up unlike most other professions.
It's a good time to be a scribe, the books of glyph mastery are cheap (10-20g) and glyphs are still worth a decent amount.
If you had a really good friend (read: a sucker :P) you could just do 1-450 using ink of the sea tradeins, which would generally be the cheapest way to go.
