I have had all theses pedals.
And yes I have had all of them fail within two years. Except the last but that doesnt fold.
Normal usage not MBK.
I currently use 5 folding bikes and I dont want to be buying new pedals every year. So they have either MKS or wellgo detachables. And I have one pair of clippless in each system also. The wellgo version can be with in your budget on ebay.
I might have been unlucky with my folding pedals lifespans, but I dont want to end up with another crate full of odd sided folding pedals again!
