hi there, i am trying to get hold of a 'dna strand' object (preferrably in .obj format). i have found a couple on a site called http://www.3dcadbrowser.com - quite good except hoping to find something a bit cheaper (scrooge eh?!). any help would be appreciated. the site i have mentioned is actually quite good except i suspect some of the models uploaded are poser rip-offs. thanks mike
