Do older wave figures come back in stock?
 

I was a bit late in collecting the origins/cartoon collection masters of the universe figures and there are a few that are really hard to get in the UK...

Some of these are main characters... 'Beast man' being one of them.

I could pay ridiculous prices to get these figures shipped to me from other countries.

When a beast man goes on sale on ebay - it's not cheap and I see it has lots of watchers right-away (because a lot of collectors like myself must be seeking him too).

If you are a seasoned collector, what would be your advice to me concerning this? - Should I snap them up now? or wait a while? Or if I wait any longer will these figures become even rarer and their prices increase even more?

When a new 'wave' is released, do the toy companies sometimes release some of the old waves with it (so that people can complete their collection or replace damaged figures etc)? - Or do they ever sell old figures with new ones as a double-pack or anything like that?

It's just a bit concerning when you nearly have the entire collection of something but you wonder if you'll ever be able to complete it.

Any thoughts on this would be appreciated.
