need help: new glasses, varilux, & online buying, maybe!

i'm trying to figure out what kind of varilux lenses would be best for
me, and a few other things as well. here's my prescription:
-2.50 = -.75 x 145
-4.00 = -1.00 x 180
+2.25 add

i'm thinking about going with polycarb panamic varilux lenses, as
opposed to plastic. what do you think? i already wear variluxes,
about two years old, but i can't remember the type of V it was (and I
can't call the store for various girl-related reasons, ahem!). is
there something better/lighter from varilux that i should consider?

actually, i'm getting two pairs of glasses, one from a local place and,
maybe, the other online. this online pair would be both Varilux and
Transitions and hopefully the seg would come in about right, because
the price is certainly right:
lensecrafters: 485
local place: 405
framesdirect.com: 298
eyeglasses.com: 265

i know you get what you pay for, but i'm thinking the refund policies
at the online places will help lessen my fears. has anyone here used
any online place for progressives?

anyway, thanks for any help you can offer.
