agreed.
there is nothing like the build....nor the enjoyment of using them.
nothing comes close.

so.
I would suggest posting your selling said units ...in the buy and sell section of the forum here.
Make a new thread in it.
post the fact you are selling ~number of units.
what comes with them.
Starting bid or buy it now price
and a link in the post to the ebay auction / sale

give the thread an update every now and then...give it a "bump"...
to keep it in the frontal lobe of those who come here...
and an update on how many are left...now and then..
and any change in prices.
and that is about it...
