Good zone for engineering?

[Bellboy]

I am a L56 warrior, with goblin engineering. Just wondering if there is a zone to go to for rep-based engineering recipes, like Silithus has the Blacksmither in Cenarion Hold? Just about to start Silithus as it has a good amount of thorium veins in it, but if there is a more 'specific' engineering zone I would much prefer to go there.

Nothing I can think of from the top of my head for the 'Old World' at least.

If you check Crafter's Tome (http://www.crafterstome.com), you'll be able to search for engineering schematics amongst others. There they have a list of all existing recipes for every profession, and where to get it - just browse that list to see which ones require rep, and you should be fine. :)
