Welcome back, Hyfe. It's good to see you again.

I started with the highest end system of that model and added on. Wound up about $2,400 but I got $500 worth of discounts.
Sub school is interesting. I just finished BESS (Basic Enlisted Sub School) and in about 2 weeks I will class up for my actual A-school, which is technical training for your specific rate. I'm going to be a T rate which is technical/electronics crap and will either be working with comms or nav. I've learned a boatload of crap in BESS about subs which I'll probably forget within the next month. I'm supposed to move to a new building next week, and once I do that I'll get hooked up to the net.
