One in good condition (water tub not rusted out) have been fetching $80-$120 depending on condition. just seems like a few years ago you could by them for $45 all day long.
I hope
@ShadetreeMotorcycle found his Empire pump. I decided on getting one on eBay but it was $145 (just under $170 shipped). It seems to be in okay shape or at least for how it will match up to my other Empire stuff.
