Help with price estimation

I've been meaning to sell off my old Transformers which I had collected as a child and I need some help with estimating what they are actually worth. I checked ebay to get a general idea about the price, but am not sure how realistic they are.
All the figures are loose and have sadly no instructions, they have the usual signs of being used, but most are in good condition.
I had asked tfsource last year how much they would offer, it was about 300$ or 400$, but I'm not sure how reliable that estimate was.
Any help and/or opinions are greatly appreciated.

Here are some pictures to help judge their value. I can upload some better pictures if necessary.
