This is confidence inspiring. Thanks.
For posterity:
- new gov from McCauley: 4300
- rebuilt McCauley from QAA or AAO: 2300, 1k core.
- rebuilt Woodward 210443 from AAO: 1800, 300 core
There is also a newer Woodward that supercedes 210443 for a little bit more. AAO and a few other sources opined that Woodwards are a little better than the Mccauley units, but didn't elaborate on how.
I went with the 210443.
