Whoo! Welcome Joshy! You can't go past G1 or Masterpiece Soundwave. If your going for a masterpiece and if you can find a Hasbro version for a minimally inflated price I'd go for that one as it was way better value. If you want Tak/Tom I may have an idea where to find one for a good price at a certain online store ;-) haha..
That sux about it being stolen, but have a chat to everyone here, everyone seems to be onto it and I'm sure any question you have it won't take long to find an answer!
