[time-nuts] Recommendations for a newbie?

[Robert Liesenfeld]

Wow, thank you everyone for the wealth of information and advice.  It
sounds like for my needs, either the TBolt or HP Z-box will do just fine,
and cost is going to be more of a driver than anything else.  It seems that
the HPs are more plentiful on a certain well-known auction site, but
Thunderbolts are cheaper.  I'll keep an eye out for good deals.

Again, big thanks to everyone for the information, and for the welcoming
atmosphere!
