I got the 25 row stillen designed one. They claim it has the same temperature drop as a setrab unit and it has been pretty effective for me.
One word of advice, the mounting bracket provided is designed to relocate the ps cooler and mount on the passengers side. I didn't want to do that so I drilled 3 new holes and mounted it on the drivers side. Pretty easy to do but I wish I knew about that before.
Stillen unit also comes with built in fittings on the core so you cannot cross thread during installation.
