Help estimating value

Hello everyone, new the forums here.
I am trying to get a estimate on a couple of my collections.
I have a complete set of the Japanese reissues 0-21 (all still sealed except for Starscream as I wanted to watch the DVD).
I also have a complete set of the US released alternators (all are still sealed except for 1 and 2 - Smokescreen and Sideswipe, but they do include boxes and are complete).
I am looking to sell both sets complete, don't really want to break it up, but I am having a hard time estimating a value as I don't see too many ebay listing on complete sets that have sold. There was one Japanese set that sold for $2226, but it was missing #20. I'm just looking for a good value on these and see if there is anyone interested in one or both.
If I am asking in the wrong forum, I apologize.
