The tool set, without the anvil holder, is listed on the Hennings site for $165.
Jeff Kane sells a similar tool set for $195. I purchased a set of Jeff's tools when he first started offering them. IMHO, they are good.
Is there really any difference between the basic quality of the Harbor Frieght and the STX-360 press? Who knows?
I think I can make out "MHC" on the STX_360.
Both presses are made in China.
Both Enco and MSC sell similar presses under their own names as "Imports"
Finally, in the Modern Era, Lionel used plenty of similar unbranded Chinese presses. Rather than being set up for universal use, as service station presses are, they were fitted with custom tools to do a specific job.
