Hello all - l'm seeking a good value automated pool vacuum. Last year, I thought I was getting one but didn't get chance to purchase - but was told that the S200 or Active20 were best value brands. Now that a year has elapsed, is there any other models you guys prefer that are value-priced? Also, as of last year, I was told that Marina Pools & Spas was a great place to shop vacs - still the case?
