Here's the pictures I promised. This is a Pentius PLB3600 oil filter. Seems very well made. Took me forever to cut it open with my Dremel. The canister is very thick. Check out the unique bypass valve. The plating is very even and there is a lot of it. Spiral tube with a nitrile ADBV. The picture of the baseplate has a plastic cover over it like DENSO's oil filters. These are at partsamerica.com for about $3.49/each. Commercial accounts like mine get them for about $1.50/each. Seem like a good deal.
Hope these pictures work.

Let me know if these pictures don't go through. I will have to send them to someone to post instead.
