An Australian manufacturer has launched an impressive line of portable entertainment units with full TV screens; some models have an integrated DVD player. Better yet, they only require 12-volt DC power and come with a cigarette lighter power cord, or can be wired directly into the boat electrical system. They draw less than 2 amps when operating. The screen is bright and has its own integrated stand or can be mounted on any of their several bracket systems. Integrated screen and DVD units come in 19 and 22-inch models at prices starting about $370. Accessories also include remote amplifiers and extra speakers.
