Extreme psi sells this also for $245. That seems like a pretty good deal considering no addition fees for the o2 sensor, control module, 13' harness, exhaust boss, and plug.
I liked the Zeitronix as well, but I really like this unit for the price. I'm not buying this or anything for awhile, but when I do I'll be sure to make a post.
