Naptech and Metric Test are good too.
Don't settle for the price in the website, easily they will come down 10-40% from that price.
We purchased some good stuff;
Used 8720ES VNA for $50K with time domain and 1 hz accuracy
Used HP Spectrum Analyzer for $14K that's good quality up to 22 Ghz.
New Antenna pedestals with GPIB control from M2Inc for $2.5K.
When I was at Raytheon, they purchased a huge amount of government equipment for $1000, including 3 HP 8510 Network analyzers that worked fine(that's $110K each) It was probably two semi trucks worth. My tax dollar tear ducts cried when I saw the waste.
