Can anyone name a couple of reasonably priced or freeware tools that
could help me measure the performance between two VoIP endpoints?

As far as ISPs introducing jitter to VoIP calls, can't this be solved by
passing VoIP over a VPN? 


Technically, yes,  but in the many cases, (most, IMHO), such an approach
is completely impractical.  The processing overhead added by the VPN is
not inconsequential. Move importantly, deploying VPN's for every
endpoint connecting to an ITSP or IPPBX could be ruinous.
