RF test equipment brand?

Currently we are looking for RF test equipment such as VNA, NFA, SG, SA ...
So far I am looking into some brands like Agilent, Anritsu. But I still want to know more about other brands. My main concern is of course the performance and price.
Any suggestion? Thanks.

Consider also Rhode&schwartz.
In my opinion today agilent and R&S are the most competitive companies for RF equipment. Both of the companies have low level and high level instruments in all brands for RF & MW.

I hope it can help.

Not for VNA's but mostly for other analyzers and equipment...

Thanks you all.

As far as I know, ADVANTEST also has the market share on ATE instruments. such as VNA, RFGen...

And I'm now using the VNA from ADVANTEST.
