its not really about how much it costs, its about what you make with it, the extra work you can do and the ease at which you can do it. ive never used a porty but to be honest i admire the guys that do, all that lugging of machinery, filling then emptyng, faux that for a game of soldiers, plug the pipe in to the fresh tank, go have a brew then come back turn it off, get to job, run pipes straight into house, clean, pack away, then pull up to the nearest toilet drain and empty, at the end of the day, clean your filters and fill up ready for the next. piece of pizza.
do it mate, ya know ya want to.
