I think you'll find that pretty true of most performance parts; there's a lot more opinions than buyers....no one has bought from them recently...
Who gave those regrind prices? I'm just curious. Remember with ANY new aftermarket cam you are probably going to need that hardened distributor gear.
That aside, plenty of things take a couple of weeks to sort out. It's the nature of a small marketplace. My biggest gripe comes when I'm not informed of delays.
The less you change at present, the better your chances of it running well on reassembly. I've seen people overstretch their abilities and budget, change too much at once and then wonder why their "fantastic" rebuild doesn't cut it. One guy didn't even know he'd put the rings upside down.
If you get it back together soon, and keep things simple, the fun will return.
