So, ok, this looks interesting. Is this something that's pretty straight forward to install yourself though? I'm ok with automotive mechanics (I like my bicycle). But when it comes to installing new things, I'm hesitant. If I was to get a mechanic to do it, how much would they likely charge to install it? If it's super expensive, for less than $30 that I found one on JC Whitney, I'm willing to risk getting it to install myself, but, if it's cheap to install it professionally, I would be more at ease with myself
