As far as I know, all TW cams are the same.
I have a webcam camshaft, stage 1, and I like it. Wouldn't mind trying their next stage up, but it requires new springs and I didn't feel like going that route quite yet. They have 3 stages available.
I think the TTR230 cam has some more duration, but for the cost of finding one you'd be better off going with the webcam. But webcams are a hard weld/regrind so if that doesn't appeal to you the options become limited.
My cam was $142 shipped to my door.
Apparently you can't link to the searched webpage for a particular bike, so here is the link to webcams:
edit: my signature has a couple YouTube videos of my acceleration with the setup as listed in the description on the videos.
