I'm comfortable with my home lab for the moment. I work fulltime and study
in the evenings. I find my rack of old equipment plus a couple of 3550's
serves most of my needs and it's paid for. For the rest I use remote racks
and usually don't have a problem getting the slot I want.
I do wonder if setting all the dynamips stuff up would be a royal pain in
the ass. I will however set one up in due course as I like the laptop idea
when you are on the move or in hotels (internet charges in those places are
not pretty).
Regards
Gary
