still, i'm at the point where i don't know whether or not to wait for the comic shop to get these in or preorder them through MR. the Luke x-wing helmet doesn't appeal to me as much as the Boba or Stormtrooper, so i can always wait to see how they come out.
I guess it would depend on whether MR has announced an edition size for these or not. If not, then I wouldn't worry all that much. If they are somewhat limited (less than 2K) then the Luke helmet will sell well, as it did with Riddell, where the degree of difficulty was highest for the Stormie and then about equal for Fett/Luke. C-3PO and Vader were almost always cheap and easier to find. I paid about $60 for each of Fett and Luke.
I'm guessing though that there's better than 5000 of each produced. Wedge's helmet is limited at 1500, so unlimited must mean a fair bit higher.
...AS mentioned earlier I could be swayed to get the stormtrooper as mine has a yellowish tinge these days...
Glad to hear it. Serves you right, you boastful bastard. 
Geez, can't you be more smug than that? You'll get pretty much the same damn thing as I bought for less than 1/3 the price even if you pay full retail.
