HMD Suggestions?

[JMOwens]

My apologies if this has been covered before, but our lab could use some advice on a new HMD. We've been using a Kaiser ProView80, but it recently died for good. We are trying out its replacement, the Kaiser SR80A, but are having some serious reliability issues with that. Unfortunately, the SR80A seemed to be the best compromise of price, FOV, and resolution.

Can anyone provide some advice about what's worked for you? We're currently considering Nviz, but are concerned about the small FOV, and Fakespace, but we found the visual quality lacking when we demo'd it at VSS. We would love to find something with >60 degree diag FOV, decent resolution, and rugged enough that we can (gently) walk around with it in a 12m x 12m VR environment.

Thanks for your input!
