Numerous vendors now have the chrome lavatube. As far as I know Apollo is the only vendor that has the SS. I got my SS mini last week and really like it so far. It's really solid and looks great. The SS ones cost a lot mOre now though bc they realized how much of a PITA they are/ expensive they are to manufacture. I got my SS mini kit for only $60 during the preorder with a coupon and now a SS kits cost $105. A bunch of vendors have the Chrome ones now, but I don't think many vendors,if any at all, are going to try to sell the SS tubes since they cost so much more to manufacture.
No lavatubes have a blue LED. The version 1.5s have an "improved" screen, but right now the version 1.5s are only in the older tube style. So if you want a chrome or SS with the much better end caps, it will have version 1 internals
