We have an 01v standard. Got it cheap about seven years ago and it still sees a lot of use. We too had to have the earth error modified, but since then has been flawless. We use it on little shows where it's nice to have a little more functionality over a little analogue. Also it very often gets chucked in the truck on larger shows. Takes up very little space, but could get you a very long way in the event of a major show-stopping console failure.
