Well, I'm currently waiting on an Encore Megatron which should be arriving sometime within the week, but other than that I'm stumped for ideas on what I should get next. Since my collection's not too large I think it's safe to list what I have. Maybe some of you guys can pick a pattern and recommend something for me.

20th Anniversary Prime (Damaged, will replace eventually)
Masterpiece Skywarp
Masterpiece Starscream
Encore Megatron (On the way, as you know)
Encore Soundwave
G1 Rumble reissue (KO, don't know if I can get a genuine replacement)
G1 Ravage reissue (KO, don't know if I can get a genuine replacement)
Alternators Sunstreaker
Alternators Rollbar
Alternators Rodimus
Beast Wars Optimal Optimus
Beast Wars Optimus Primal (My oldest toy, got him in 1996. Missing a cannon cover and can't find a replacement to fix it )
RiD Optimus Prime (Damaged and missing a few parts)
Armada Galvatron
Titanium Rodimus
Titanium Thundercracker

I was thinking maybe something from Binaltech but I've heard some of them have paint chipping issues. I'm not really into Classics, although I might pick up a few of Takara's, but any suggestions are greatly appreciated .
