Another vote for Progressive Industries EMS. I've had 2 (so far), a 30 Amp pole mount and currently a 50 Amp hard wire. If I need to buy another (maybe for the next TT, let's say) I'll lean towards another hard wire. Depends on the space available to install it. A recent post suggested there is usually room behind the converter panel.
