Looking for camshaft recommendations

[pjmoreland]

Several lobes on my camshaft are severely worn. I'd like to replace the camshaft with one that is pretty much stock and will hold up ok. Any recommendations? I don't want to spend a lot of money.

For anybody who is interested in knowing how I got to this point, check out this previous thread:

The exhaust lobe for cylinder 4 is pretty much totally gone. The exhaust lobe for cylinder 8 is about half way gone. My guess is that the head gasket blew partially between cylinders 4 and 6 because the exhaust valve in cylinder 4 wasn't opening. That allowed coolant to start leaking into cylinder 6, causing the valve to crack, causing the low compression in cylinder 6. Not sure why the exhaust valve in cylinder 8 cracked.

Here's a picture showing the absense of a lobe for the cylinder 4 exhaust valve and a picture of my timing chain that definitely needs to be replaced:
