I got my new oven today!
Thanks to @jlesser, I ordered this new oven from Amazon and it looks to be of better quality than the NuWave. Its bowl is glass, not plastic - the one thing I was concerned about was how large the bowl is - it appears to be as large as the NuWave.
I’m so glad it FINALLY came!
This is the one I ordered: https://www.amazon.com/gp/product/B014UO0KW4/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
