I'd go with the best you can afford. The Square wave inverters are very 'dirty' and cause various problems on some sensitive kit. Things like your camcorder will be fine if charging when switched off, but some laptops really don't like the crap the cheap inverters put out.
Also consider getting one with a built in shut off if it detects the vehical voltage has dropped below a set level, as they will prevent you from getting stranded with a flat battery! Or at least having to kick the family out for a push start...
