Here are the goalies I think will be available (not including pending UFAs like Bishop, Condon, Darling, etc.):
ANA - Tokarski
ARI - Domingue
BOS - Khudobin, Subban
BUF - Ullmark
CAL - McCollum
CAR - Lack
CHI - Glass, Carruth
COL - Pickard
CLB - Korpisalo, Forsberg, Dansk
DAL - Niemi, Kiviaho, Lagace
DET - Howard (or Mrazek, but I think they protect him), Coreau, Pasquale
EDM - Brossoit
FLA - Luongo, Brittain
LAK - Zatkoff, Campbell
MIN - Stalock
MTL - Montoya
NAS - Mazanec
NJD - Wedgewood
NYI - Halak, Berube, Gibson
NYR - Raanta, Hellberg, Skapski
OTT - Hammond, Driedger
PHI - Stolarz
PIT - Unknown (no eligible goalies other than Murray - they'll either sign one to expose after buying out/trading Fleury or they'll make a deal with Vegas to not take exposed Murray).
SJS - Dell
STL - Hutton, Binnington
TBL - Gudlevskis
TOR - Sparks, Bibeau
VAN - Bachman
WAS - Grubauer, Copley
WPG - Hutchinson
I think I take Grubauer - Washington's best other player likely to be exposed is 35 year old defensive defenseman Brooks Orpik.
And Raanta - though NYR's best likely exposed are Klein (unless they do something with Girardi or Staal's NMCs) and Fest/Hayes/Grabner/Lindberg at F.
And Howard? Detroit's going to have some decent skaters exposed as well - Helm, maybe Ouellet or Kronwall?
They have to take 3. Maybe they like a skater over one of those goalies above - or they make a deal to not take one.
And then there's the UFAs - but why bother with a big name if you can get Howard, Raanta and Grubauer. One of those guys will be traded (or have to clear waivers) before the season...
