I would avoid old American, unless you are VERY savy working on them.... I went that route with an older south bend tool room, and spent more time working on it than with it....
I would look up Mathews precision.
Look for a SBL heavy 10 inch with a 2 1/4"-8 spindle nose or a 13 inch with the same. The larger bore thru the headstock is something you'll be glad you have.
If you come across a Hardinge HLV under $5k please PM me.
