Hello There,
I was also looking for a pair of them. Took me a while but THX
does still have them (no longer free though..bummer!).
They're available at the THX store (I wanted to post a direct link
to it but the site here says, "You are only allowed to post URLs once you have at least 3 posts. If you are a spammer, please go elsewhere. If not, sorry for this issue the spammers have made for.")
So...looks like I'll have to post '2 more messages' before I can do
that.

Oh..well....the things a body has to do to help folks out...
When you finally do make it to the THX Store, please be aware that you have to create an account to order them..no big deal there.
The only downside I've noticed is that they charge an exorbitant amount
for shipping... the glasses themselves are $1.99 per pair but the S/H is
$11.19 for a total of $13.18!!

Still....for those who have 'spent the coin' for a HDTV like either a Sony or Sammy, $14 +/- is going to be chump change.

Hope this info helps folks out. I'll post again after I've received the glasses
and let you know how long it took, etc.
