Im really curious which scales the most accurate.I weighed myself on my home scale last night before we went to Costco its a cheap WALMART $9.00 SCALE it said 199 I went to Costco & weighed myself on to differant scales the healthometer a $39.00 scale it said 197 The other scale was a DUET $56.00 scale its supposed to be accurate as the DR's its a digital but also has the circle of weights too It said 195.5 which one should I believe are the cheap $9.00 scales as cheap as there price should I get a more expensive one?I like the digital one because theres no squinting to see where the arrow is Why are all scales differant on your weight.Which one should I buy do you have any recomendations on any scales???? Thanx
