You might try your local Thrift Store. Not only do they get older
Models, but they are a Lot Cheaper for someone with a limited Budget.
When you pay $25 for a replacement, give it a couple of good deep
cleanings, and then mark it up so you can use it. Use it until the
Budget allows the purchase of something New and more to your liking.
Think of the Replacement Oven as a Temporary situation.
