Now I understand how you guys can afford all your crap. Damn you talk about living off $400 a week being tough, my paychecks during the summer at BEST are $400 every 2 weeks! Granted those are only 30 hour weeks, there is no way in hell I'll ever be able to do 40+ hour weeks at McDonalds. Now that I got my 2nd job @ 9.75 an hour and college is starting i'll be making around 250 a week, living at home. So you guys gotta be happy with your checks. Granted I live at home and my cars paid off but I still owe State Farm 140 a month + gas + other random mantinence and stuff.
As to the topic at hand, I'd say go with the sprinkler job. The pay might suck at first but with all the ammenities you get plus the fact that it sounds like moving up paywise is fairly easy, it'll probably pay off in the end AND be more enjoyable than your current or alternative situation.
