HELP! I don't own an Optimus Prime!

Hi all. Just been drooling over Seibertron's new Movie Optimus Prime Leader class gallery (that was quite a mouthful), and it's occurred to me that, despite being a massive TF fan, and with the exception of an old G2 figure in the roofspace, I don't own a single Optimus Prime!!!
So now I'm seriously tempted to buy several of the Prime incarnations featured in said gallery. It goes without saying I'll be getting that Leader class Movie Prime, but I want some advice and opinions on the other incarnations.
1. Is it worth getting Voyager AND Leader Movie Prime? I like the look of both, but maybe theres a crucial bit of info that I'm missing! Leader will have lights and sound and be bigger than guys like Ironhide and Ratchet, but Voyager has two huge guns! Both then?
2. I think a Masterpiece Convoy of some description is needed, so can anyone tell me which Masterpiece Prime I need to hunt down to get a black laser rifle instead of the silver one? Or can the silver one be easily resprayed without ruining it?
3. Is that KISS Players Convoy in the pic or Alternators Prime? It looks like KISS Players Convoy to me, what with the yellow eyes but I'd like to be sure. I'm a bigger fan of Takara/Tomy's work to be honest, but are the paint applications THAT much better to warrant the extra money?
4. How hard and expensive would it be to track down and buy some of those other primes? Like Star Convoy, Powermaster Prime and the original G1 Prime?
Any help is appreciated!!
Oh one more thing, I recieved my BINALTECH & TF COLLECTION COMPLETE GUIDE from HobbyLink Japan this morning. It is one fantastic book! Even though it's all in Japanese and so I can't read a thing, the photos and concept drawings are stunning! If you have any spare cash and like the Binaltech range - I strongly recommend this book!
