I got a T-34 Optima battery for $135 about a month ago, I too wanted one for a long time. The yellow tops are a dual purpose battery, not as many amp-hours as a true deep cycle battery but about three times as many as as a normal starting battery. I use my van for camping, and sometimes run several accessories including laptop, cameras, iPod, and GPS.
