My yay to nay is constantly chug figures, lately notably menasor and defensor (i still have takara superion just because it's better than the other 2), and will be getting UW devestator too to sit in my mp area. Whenever I get into the lines i always end up disappointed, from classics autobot cars/jetfire/seekers right up to reveal the shield, i get in, then later offload them.

As for nay to yay, I'm in the same boat about Goatwave, I have a gift card from work so I may just pick him up, if I can bring myself to justify having 2 soundwaves and 11 tapes... (Second mention goes to MP acid storm. Some people might think why would you not like him? But i sold the first one i bought, still sealed, then picked one up cheap from tru online (paid <80 each) and the box was beat up so I decided to open and display it but still intended to resell. Now he's my favourite seeker and one of my favourite MPs, pity I cant be bothered playing too much with him, that transformation).
