engine parts vendors???

hey all,

I'm planning on rebuilding the bottom end (main and rod bearings) of my '95 Cherokee 4.0L 6cyl. The dealership wants an arm and a leg for the parts (as usual) so where can I go? The only place I've found online was NAPA. They sell a kit that looks pretty good (rod and main bearing plus the oil pump ~$160). Are there other online or offline resources I should check out? I'm in northern virginia (Alexandria).

thanks,
