I know what ya mean!
But FINALLY I found one on EBAY a couple of weeks ago and paid the paltry price of ... yes, you will be reading this right .. $13.00 US .. for the BinalTech version and STILL in the box.
I am amazed no one found it (but in all fairness the guy didn't list it well since it was hidden amongst pages and pages of a Transformers search) and consider it my biggest EBAY purchase coo ever. I can't wait to have it here soon!
Check EBAY again or I'll see if the guy has any more left for you.
