The Hipshot Triple Lockdown are similar to the ABM single-string bridges (which I have experience with, and like) but I haven't used the Hipshots specifically.
The thing about both of them is the precision required when routing for them; if you get the screw holes drilled wrong, your spacing is wrong. Another consideration with Hipshot is that they're designed to have a little recessed spot on the front of the body, and the ferrules that go through the body have to be perfectly aligned from front-to-back, and they require counter-sinking on the back of the body. You're also limited on the thickness of the body you can use (any standard Fender thickness body SHOULD work, but I'd have to double check my facts on that to be 100% sure)
The ABM could easily be installed by a novice, provided they had a nice drill (preferably with a brad point drill bit) and were very very very careful to get all the spacings exact, and are willing to dowel/re-drill if you get it wrong the first time.
The Hipshots are a much more lofty endeavor to install, even for someone that has experience with such things.
If you like Hipshot, their A-Style bridge is pretty sweet, and their B and D style bridges certainly don't suck either. I'm not personally a fan of Badass bridges, but I don't think there's anything objectively wrong with them. They do the job very well, and a lot of people really like them.
