Since you're familiar with Transformers, some fun facts:
-the original G1 Jetfire is an actual Macross VF-1 that was rebranded by Hasbro for Transformers. the Vf-1/Jetfire was created by Macross Mechanical designer/director: Shoji Kawamori
-Shoji Kawamori also created the original G1 Optimus Prime and many of the original transformers. (he's like a god in japan)
-For MP Transformers line, Takara asked Shoji Kawamori to design MP-03 Starscream. the
interview was translated on Seibertron.com if you're interested in quick read =)
these VF-31 were his latest design and probably the best one since the VF-1.
if you ever want to dip into a Macross, i would start with the iconic VF-1 toy that you initially commented on. not sure your budget range, but it's going to be priced around 160ish plus shipping if you get in the early pre-orders coming out in a few weeks.
