good evening or afternoon andy, from my view you are very successful in this business. With a professional company and approach to business and all these options as to what WFP to buy, i was wondering what type of system you have, who you bought is from and why you chose it? What was your after sales service like? I now have my safe contractor accreditation so will be definatly be consuming a WFP van mounted system in the new year. I Have done the WFP couse at the BWCA and was inmpressed with ionics equipment but feel it can be a little to pricey. i have been considering the thermo pure to give my business another USP. is it woth it, i feel i maybe streching the boat a little. If you could advise, once again i will be extraemly appreachiative. regards reece
