Hi Dick,

Castle 85HV - readily available
Castle ICE 80HV - recalled
YGE 90HV - more $$ than Castle and harder to get ( but more coming to me this month)
Jeti Spin 99 - more $$ than Castle and spotty availability from importer
Schulze - ??? New controller for F3A about 15 months late already. last I was told was 2012
Kontronik - more $$ than Castle (2X +) not sure about availability in US
