Are your lines true isolated ground (i.e., grounded to the service ground buss where the power first comes into your main service box at the meter)?
If so, an Ebayer "polkmx" sells cryo'd Hubbell "HBL-8100IG" receptacles for $23.95. He sells other cryo'd Hubbells but these isolated ground receptacles are the only ones I've used.
I'm very satisfied with them.
