...the Bushnell 8x42 NatureView Porro cheapie bins seem to fit the bill as they claim 8.2 deg true field, 16mm ER and twist up eyecups at 100 dollars or so.
There remains the question if they are good enough for your taste... if you try them, let us know...
Yes, those are good, at least in the previous incarnations that I've tried. Here's the current model

Also consider the even cheaper Bushnell 8x42 Legacy porro with its similar specs. Not a bad bin.

But I've never been as impressed with either of these as with the Nikon 8x32 EII, which optically is different but in the same league as the 8x32 SE. I think of the Bushnell porros as alternatives to something like the Leupold Yosemite or its equivalents.
