FRG720CF35SP (Profibus): $2,473

FRG720CF35D (LCD display): $1,999

FRG720CF35 (just D-Sub): $1,809

FRG730CF35SP (Profibus): $2,795

FRG720CF35D (LCD display): $2,364

FRG720CF35 (just D-Sub): $2,136

Doesn't interface with Agilent Turbo, so seems that they need their own controller

Agilent AGC-100, controlls one gauge: $1,377

Agilent AGD-100, just a display: $1,069

XGS-600 Vacuum Gauge Controller (can control many gauges, no clue what product we want): between $1,200 and $6,000, intuition says around $4,000 for our purposes)
