Okay, don't hate me for this advice...but I'll bet that if you wait another few months, you'll get one a lot cheaper. These things go in waves- people get excited about a certain colour and it becomes very in-demand...then people think,"Oh, it's worth a lot, I should sell mine." This causes over-saturation as well as overexposure so not only are there more available, but people are bored and move on to the next hot collectible.
This happened a few.months ago with Magenta, and even Flat Brass Firsts where suddenly they were popping up everywhere for a while and prices kept going down.
Be patient...it will be your time soon enough- and you may not even want it anymore once it becomes easy to find!
