Had the ARB twin on the last jeep; bought the 450p this time around... it hasn't let me down yet, and is still faster than most of the other compressors out there (especially being 100% and not having to give it breaks in between)... but that being said, I really wish I'd just got the ARB twin...
Personally, I like the stinger as it's just visible over the hood from the drivers seat - turns into a good reference point for knowing how close I am to something and if I can make a really tight turn or not.
I've made periodical stops by here before as a guest, thought it was fine time I made it official and registered as a user.
So hello to all from Livonia, MI!
