Check out the site:
www.aircraftresourcecenter.com There's lots & lots of techniques in their technique section pertaining to aircraft modeling which are great for macross models.
Other than that I can think of cody's groove, which has a section on making the strike valk and bunch of other anime modeling in great detail.
To save some $$, get through these sites and they should give you a good start.
The american magazine, fine scale modeler is not too bad. Check out their web site first.
I've been with them for 3 years. They pretty much "cycle" through topics with some updates. I mainly get it so I have some stuff to do before I go to bed.
Hope that helps. There are many other sites. Check out the links of MW as well. Good luck and experiment with some piece that you don't care as much first before you dive into your "love"
