Alternatives?

So my chain has pretty much ran it's life.

I figured I'll buy the DID 525 chain (or maybe EK... I always liked EK).

Now I'm trying to decide where to buy a rear sprocket.

I currently have the Supersprox Stealth sprocket on there and I would like to get another one, but hot damn it is expensive...

Anybody know where I can find it cheaper than this?

I use http://www.ktmpartspitstop.com. I generally find them cheaper by a few bucks. Cheaper if you choose one that's not orange.

but it looks so much better on my SDR haha
