I asked a similar question here and you can read the posts since then.
Looks like I might end up getting the Panasonic BDT110 because it has the Avatar 3D BRD with it after a rebate (which can be sold if you don't want it). Cheapest price I've found for it so far is about $107, but I don't remember where that post is.
NewEgg has some LG's in that range that are rated high there, but no one has mentioned them since I've been on this thread.
GearXS has some Insignia players (I mentioned in that post URL above) from $49-$65 but they are refurb's. New price on those are pretty expensive from $100-$200 more depending on model. If you get a BDT110 and sell the Avatar 3D disk for about ~$40 that could make it about the price of the most expensive refurb Insignia......
I assume a BDT110 is "better" than an Insignia NS-BRDVD3?? "Bueller? Bueller?"
The NS-BRDVD4 sounds like a "higher" model, but it's cheaper there. FAIK the NS-BDLIVE01 is best of them there. Sears has that one for $100+ and it's an "open box".
