Mcgyvr, I see what you're saying.
From my personal experience, I used to buy cheap to save costs, upgrade tanks, and spend more on cheap things, thinking I was saving money.
What I had not realized was, if I would've just spend the extra $50 on a more reliable piece of equipment, used or new, I would've been able to use that on the next tank.
I also realized if I buy slightly or totall overkill, it would allow me to save money when I do upgrade as I'd just have to buy another of what I was using. Things such as an MP10 or LED's for example can be tuned up or down for the tank needs. That's the beauty of these things!
