I've used the Tronic heater guards even with Stealths and I'm using one with a 400-watt Hydor (one and a half, actually---the heater is too long for one guard, so I bought two and used part of one to lengthen it). If the Neptune isn't really thick, it would probably fit into it---you'd have to check the length of the heater against the guard, though.
You could also make one from PVC pipe (drill holes).
