chogoking

Hello, newbie question here, this is my first post. While I have been familiar with Macross most of my life, and even owned many toys, I am still very much a newbie compared to many members here. Hopefully someone will be willing to help me out and point me in the right direction. Recently the Bandai DX Chogokin line has caught my eye, I am no stranger to bandai or chogokin, I own most of the SOC line and others, but have yet to try out a DX Chogokin Bandai Valk. Would you concider this line to be generally worthwhile? If you were to start with one, which would be your first buy? Any I should avoid or save for last? Also, its tough to find a list of all releases in this line, anyone have one or could point me to the right place? Are the older releases impossible to find? I tend to be a completist when it comes to awesome toy lines, just want to see what I'm starting here, lol Anyway, I imagine I will end up checking out at least one of these, thanks in advance for helping guide me to a worthy first purchase.
