My wife and I bought a house last October in middle Illinois with a pool, the pool is 10 yrs old and it has been well kept. I had a local dealer closing it in late October and we are in the process of getting ready to open it up. The current pump is original, it is a Pantatair single speed and I'm seriously considering changing it to a variable speed pump, either a SuperFlo VS or a IntelliFlo. I have request quote from a vendor for a IntlliFlo pump and they quoted $1,800. I have seen some prices on the internet for the same pump for aprox $900, when I asked the vendor for the difference he warned me of issues with warranty and reputable vendors on the internet, mostly "used" equipment. When I looked at the work involved to do that job it does not seem that complicated, I consider myself handy and think I can do it. I would like to hear some feedback regarding internet purchased of this type of equipment, if there is a few recommendations regarding internet vendors, I would like to hear about it. I also like to hear if somebody has done this and can share some learning. Thanks,Luis
