The old iron US and Brit push pull single end tenoners are solid machines but not very versatile or easy to change from one profile to another. They are from an era when products were made in mass quantities. Today it is all about being effective at one off and small batches.
Tooling is more expensive but sliding table shapers will run circles around the old iron tenoners. If you want to step up from that look at 80s and 90s era single end tenoners from Europe. Panhans, Okoma Kolle etc. and a step up from that are modern day CNC tenoners from Europe.
For home hobby use or small pro shops a sliding table shaper is versatile and effective.
