I purchased a Space vac with 40ft of carbon fibre poles, loved it, it's easily paid for itself already and only had it six months, it's a good enough system.
Slight negatives are most of the time you have to get your hand in the gunge to allow the water to properly drain away, also, you must clean the poles out each time of use as any debris causes the joins to stick, once they are clean, they're a joy to put together.
