If it's model kits that you want, Hasegawa's non-transformable kits are right on the money. They're kinda big too with the 1/72 scale. My favourite is the YF-19 and VF-0S fighter kit. The only transformable models that I know of come from Bandai. They're reissuing past models at the moment. You can buy or find out more about it at www.hlj.com.
Though in my opinion it is a good investment (as well as satisfaction) to save up for a Yamato toy. The new 1/60 VF-1S looks like a winner, though you might want to wait a bit for a review from those who'll get it soon.
Other senior members on this board might give you a better or precise advice though. But here's mine: Take your time and try to find out as much as you can before you buy. And buy from stores like hlj.com or from straight shooter members here. Avoid eBay! (maybe it's just me but I've had a bad experience shopping there)
Edit: You might want to wait a bit for Bandai's 1/72 Macross Frontier models to come out. Not sure when that might be, but it'll give you more time to save up for it.
