Registry for Big Appliances

So I was talking with my sister, and I told her I wasn't doing a registry because we have a lot of household items that are usually on registries.


One idea I had was putting a money jar for our honeymoon, but we ended up booking our honeymoon already and chose a cheaper destination than originally planned (though we may have to cancel honeymoon - currently at the mercy of Westjet).
Our house came with not very good appliances - fridge, oven, washer and dryer are all used and in poor condition. Our fridge is falling apart!
My sister suggested we do a registry for appliances that people could pay into with whatever amount they choose. I like that idea, but I don't want to make my family and friends feel pressured to give a bigger amount of money due to the registry items costing more.
Should we do a money jar, or has anyone heard of registries for something like this?
