900 Watt element

[PowerDr]

I was reading about all the heating element mods people have done and I was thinking about either adding a 2nd 500 Watt rod, or getting the 900 Watt element.  I saw that some people have gotten the Tempco 900 watt element at Granger.  I searched and found the one at Granger for $127.70  Seen here https://www.grainger.com/product/TEMPCO-Finned-Strip-Heater-2XEF3

When I did a search for that part number I found this one at WalMart for $39.33 seen here https://www.walmart.com/ip/TEMPCO-CSF00131-Heater-120V-12-In.-L-1200-Deg-F/40748741?wmlspartner=wlpa&selectedSellerId=1122&adid=22222222227028244275&wl0=&wl1=g&wl2=c&wl3=60529086129&wl4=pla-95223148569&wl5=9021827&wl6=&wl7=&wl8=&wl9=pla&wl10=101593696&wl11=online&wl12=40748741&wl13=&veh=sem

They have the same part number but a huge price difference.  Where have you, that have done this mod, gotten your elements?  It seems weird that there is that much of a price difference for what appears to be the same part.

Thanks

I have the extra 500 mod on mine but the price is right and the part is the same. go for the Walmart part and buy an extra for a spare, you still come out ahead
