I suppose everyone has an approximate ceiling on how much they want to spend on grease.

I used to like saving a few bucks, but now it is less important to me -- I don't mind spending twenty dollars or so on a fourteen ounce tube of excellent, high-end synthetic grease. I can get a 14oz tube of Lucas Xtra Heavy Duty Grease for about $3.92, which is an excellent grease too; but perhaps the Red Line CV-2 or the Swissmade Motorex 2000 is a little bit better -- perhaps, perhaps not. We don't know for sure, at least at this point, for these applications.

But I see no reason to spend more than that. In fact, since the Lucas grease passes requirements for NLGI CG=LB and is made with a polyurea base, I'm not sure it's worth even stepping up from there (assuming it is an actual step up, in practice). Maybe, for me, it's worth going up to the $15-20 level. Some of those greases might be just a bit better. Maybe, maybe not.

Not sure the Park Tool HPG-1 synthetic grease is worth the extra. Maybe. I spoke with Park Tools tech support, and it is a superior lubricant compared with their standard (PPL Polylube 1000) grease.

But at $12.55 for a four ounce tube, is it worth it?

$12.55/4oz = 50.20/lb, or about $43.93 for 14oz, which is 2-3 times the cost of some of the other high-performance synthetic greases. And over 11 times the cost of the Lucas Xtra Heavy Duty polyurea grease. The Lucas grease is an excellent and fine choice for these applications, possibly even as good as (or even better than) some of the more expensive options - more expensive is often assumed to be better, but often isn't.
