I have them and they work well. I don't have anything to compare them to, though. I have an Optoma HD3300 projector and with these glasses I see absolutely no ghosting and I can go grab a beer, tilt my head every which way and not lose sync. When I turn the lights on, they do tend to flicker, but I think that's going to happen with any DLP link glasses. At any rate, I ended up buying six of them if that's any indication of how much I liked them. Buy a pair and see how you like them. They're really affordable, and if you do like them you can pride yourself in the fact that you saved a fair chunk of change relative to other glasses.
Personally, I won't go for rechargeable. Just get a handful of batteries from the dollar store in case a pair dies and you're good to go. I'd hate to be in the middle of a movie and have one of my buddies' glasses die and have him not be able to watch because the glasses need to be recharged. Plus, there are a finite number of recharges, whereas I can always buy a new battery. Mind you, by the time current rechargeable glasses die my pj will probably be tossed in favour of passive Dolby 3D, but meh.
