The spec on that one is SWR<1.2 which means a 20% tolerance, or resistance from 40 to 60 Ohms.
Most of my 50 Ohm loads are much closer than that.

Link on eBay for a 5W BNC dummy load with heat sink for $9.75 delivered from China. You will have to wait a few weeks to get it. This is typical pricing from many Chinese sellers.
A name brand, like Comet, will be a few bucks more, but will still have come from China, or other Asian country anyway.
As others have noted, DON'T use your calibration standards for anything but calibrating your VNA.
