Yuasa is a great battery....with some online shopping you can get into one for ~$70 last time I checked.
I've bought mid grade stuff...like a Moto Master and had it fail after very little use (0 volts from a broken connection internally). I've had better luck with the no-name stuff on ebay...I bought a few from a seller called Battery Geek and they all worked well and lasted a few years (the couple I have are still going, 3 years now)....he's no longer a seller now.
I bought a Shorai for my zx7r project off an ebay seller...$116 shipped. it is stupid light and cranked that motor over effortlessly....its only a few months old, so I can't comment on longevity. its hard to believe that a 1.5# battery has that kind of power in it. They also have a longer warranty than the lead acid batteries, and claim to not need winter storage care.
