Non macross favorites:
Kaiyodo "Big Guy" Godzilla. The four foot tall one. I bought it on ebay and the guy wouldn't send it to me for weeks. It was a lot of money, so I called him and threatened to call the police. It was GRAND LARCENY, after all. I received it three days later in a refrigerator box.
Hyper Hybrid Gundam RX-78
I'm not religious about this mech like some people seem to be, but it's three feet tall, weighs twenty pounds and is as poseable as a MSIA. As Ferris Bueller would say, "If you have the means, I highly recommend picking one up".
Macross- I guess it's the Bandai reissues. I've got all the 1/48's and they're the most beautiful, but after seeing the Bandais for years on the net and at toy shows for hundreds of dollars and then being able to get each for under a hundred in every import store you walk into, I guess they pack the most punch. Looking at them all lined up on the shelf, it feels like that dream I used to have about walking into a Toys R Us in 1980, being able to buy all the vintage star wars at retail and then being able to take it back to the present with you. Chunky Monkeys, indeed.
