i had one of each and love them, only thing ive heard is they may need a bi-yearly cleaning. but for a 1/4 of the price of a vortech its worth it to me. by all means if you have $400 to spend on 1 Vortech go right ahead, it will probably last you longer and it is a better pump with more features, but i can get the same wave effects with the wp 25's & 40's, for a fraction of the cost, im willing to take a chance.
