Two comments:

You may be able to buy a one year old ANA from a leasing company at significant
discount. Call around.  They go stale faster than donuts.

Be aware that modern ANAs use lots of custom MICs and special assemblies. If one
dies, it can cost a not so small fortune to repair. In one case, I an HP
generator (5.9 to 6.5 GHz) with a bad output amp. They wanted $1300 for the
module and urged me to buy it quickly before the part price went up. I declined
and opened up the module case. There was a loose screw inside. HP refused to do
anything, even though it was obvious that the thing was defective in original
manufacture. Be warned.
