$1000+ is high, but that is the fault of Canadian import duties. Question: does that $1000+ price include the GST? Then provincial sales tax on top of that?
Here in the US we paid no sales taxes as this was an interstate transaction and the seller has no physical presence in our state; no sales tax collection agreements. Plus $100 freight costs.
Note regarding the linked to compressor. A big part of what makes these efficient is the electronic control box, which is not included in that link. The controller allows a soft start reduce power up surge and programming the run times, motor speeds, etc.
That compressor technology is not new. ARB and Engel were using it 15 years ago.
