Battery Shutoff Switch

[Okiedoke]

Before I start replacing the O2 sensors, I need to disconnect the battery. So I've been giving some thought to what to do about the battery. I don't have enough clearance in the garage to open the hood enough to have it propped open. With the front on Race Ramps, I'd have even less clearance. That means I need to disconnect the battery outside the garage and then push the car back into the garage and onto Race Ramps, which is going to be painful and can't be done on stormy weekends like this one. I'd have to do some work in the future that involves electricals too (radio, window, etc.), so I'd have to do this multiple times.

It seems like this would all be much simpler if I installed a battery shut off switch. Due to the battery location, I can easily open the hood just slightly to connect/disconnect the battery, even on Race Ramps. I was wondering if anyone had experience with these and which switch to get?
