Well I've been wanting one for a good while now and am finally going to go out and pick one up. I have a question though before I make the purchase.

Requirements:

-Ingersoll Rand
-2 stage unit
-60 or 80 gallon tank

Question:

1. I have found a variety of pricing but some of the 80g tanks say "fully packaged" and contain a automatic tank drain, aftercooler, and low oil level switch. Do I need these? At what point does the tank need these? (I believe it has something do only with the 7.5 hp motors?)

I didnt want to get a husky, retail brand, etc. strictly because of quality. I like the idea of the 7.5 HP motor because of fill up time and CFM output (I could run two guns at once)

Thanks ahead guys!
