Hi eric,
we are currently using Pharmacia Novablot and Pharmacia/Hoefer TE77. Both 
work well, but the latter one has the big advantage of using coated 
platinum plates. They are far longer lasting than graphite. I would 
recommend to stay away from graphite plates since their life time is very 
The TE77 and I think also the TE70 uses  a gas trap, which means less 
problems with bubbles during transfer (although I find this a minor problem).

Hope that helps
