I agree with manwon, having shot with the star and lucky cues only on occasion there is a marked difference (I shoot full time with two mcdermotts).
If you choose to go that route however, there are many sellers on ebay. Haven't seen any AzB users dealing stars here but of course, buy from your fellow users when you can! =)
The ebayers (some of whom are AzBers) are holding no minimum bid, no reserve auctions for the star cues. I've been tracking them over the past week just to ascertain market value. They're consistenly going for under $50 including shipping, most with j/ps and from authorized dealers. There also seems to be multiple auctions for them ending every few hours.
If you don't mind waiting around for the right opportunity and your guys don't care about the looks of their cues, plain jane entry level mcdermotts are also going for around the same circumstances and prices. I believe there is an AzB user "donthat", who has the same ebay account name, who has been selling them off like crazy.
Any route you go, good luck with your purchase! =D
