That makes sense in a simple, back-of-the-envelope F=ma sort of way. I hadn't really thought about it from a safety perspective, though; it just suits my needs

That makes sense in a simple, back-of-the-envelope F=ma sort of way. I hadn't really thought about it from a safety perspective, though; it just suits my needs well. In general I'm happier to economize by buying really nice stuff that's cheaper because it's used, than by buying something newer that's just cheaper. It becomes an aesthetic thing - a feeling of shabby luxury suits me.
