I've noticed the Sig inventory everywhere is struggling... hmm.. How about a Super Sportster .60. Tower should have those in stock, and these are good kits to get your feet wet in building... or an Ultra Sport... all Great Planes kits...
The Ultra Sport would actually be a step or so up from the FourStar.. as the Ultra has a tapered wing, and is a bit more aerodynamic..
Hey.. A link just came up that just might get you what your looking for... as it says "in stock".. apparently direct from Sig. Have a look...

Good luck.
