the samsungs are good if you ever intend to have large viewings. for 6-8 pairs, it's probably best you only buy one or two 'nice' ones, and spend 15-20bux a piece on the rest. i mean, they still work and function beautifully. they just aren't as sturdy, and let some light in from the side.
i bought an f8500 that came with 4 pairs of the 5100's, and honestly some days i prefer them to the jvc glasses. they are really light, and seem less intrusive.
