If you don't value the testing Colcrys did (I probably wouldn't, colchicine's been around long enough), consider getting it from a "Canadian" pharmacy online. Generics of otherwise patented/exclusive drugs in the US are frequently legal in other countries. I know of a number of people who order from an online "Canadian" pharmacy for a generic version of Singulair, which is produced in India.
The legality of importing these for personal use is pretty murky. The FDA probably wouldn't like it, but it's not a blatant violation of any laws I'm aware of either.
More generally, I really struggle with patent protections for pharmaceuticals. It's difficult to imagine how they'd justify paying ginormous amounts of money to develop and/or test products to the FDA's standards without patent protection, but I find the idea of patents pricing people out of medication distasteful.
