Hello Bato and welcome.

Yes it is a fantastic time to be a collector, particularly of G1 Transformers. Between Masterpiece, Combiner Wars and now Titans Return there is no shortage of plastic to put on your shelf. Are you sticking to Combiners or looking to branch out into the other lines? I have to say that once you've had a taste for the Masterpiece figures it's hard to pass up on them.

In terms of costs, one thing that can help get the most bang for your buck is to pre order them at the early bird rates either from local online retailers (Eg Premium Collectables) or overseas online sites in Japan, Asia or the US.
