Need to purchase teaching mannequin--ideas?

I looked at the Susie Simon
http://www.gaumard.com/viewproducts....&idcategorie=7

It has lots of options--I want the IV access arm, male catheterization adapter, and the injection sites, in addition to the basic model. I'd use this for teaching purposes at community health fairs, nursing conferences and with attorneys involved in med-mal cases.

The base price, and even the add-ons, seems quite reasonable--but does anyone have any idea where to get such a mannequin even cheaper--possibly, gently used? I am in solo practice, as a legal nurse consultant.

Seems like there should be a whole glut of such mannequins out there at deep discounts, now that teaching hospitals and nursing schools have access to SimMan--

Thanks so much!
