you pay for what you get mate but i wouldnt. I spent 4500 squid on an ionics system and had it fitted in my van got 2 poles 12ft and 30ft a safety sign and the best advise possible (from those who have been in the business for years,) and im well happy with the service i got and the system, its already started paying for itself ive picked up loads of work since i bought it and ive only had it 2 months if you want to get all the best contracts you,ve got to look the part so invest in a good system where you have good aftersales service and dont go for the cheap crap.
