HI!
I have decided to purchase a spaceball for manipulation of the models in
VMD. I was wondering if anyone has experience with the different models,
particularly the difference between the HP 2003 A4360A, the 3003 models, and
the latest 4000 flx models. All of these are available on ebay with the
2003 going for less than ~$40, 3003 ~$60, and the 4000 >$200. Huge
difference in price for 4000, but is it worth it? Any advice on which model
would do the job and is easiest to work with would be appreciated.
Thanks,
Jill
