Been waiting since the downfall of Nalgenes to jump on Sigg's train? Get to a computer or nearest "outdoor lifestyle" store stat -- apparently the lightweight, crack-resistant, reusable, and recyclable aluminum bottles are in such short supply that even the company's own online store has halted sales.
"Due to the incredible demand for SIGG bottles, we are forced to close down the MySIGG shop. We are also unable to supply any other Internet business for Sigg Brand. Our Swiss factory is working around the clock to produce and ship more bottles to us, but the demand has currently and for the near future - exceeded the supply."
REI, EMS, and LL Bean all seem to still have the bottles in stock (online and off)...I might just buy a few to auction at eBay!
