Ameda vs Medela

I received the Ameda Purely Yours through my insurance. My little one is now 6 1/2 months and my supply has taken a drop. I've done everything to increase my supply with no luck. Fenugreek, brewers yeast, oatmeal, mother's milk tea, more water and massaging as I pump. The lactation consultants don't think it's the pump but I think if I got the Medela I might see a difference but I also don't want to waste money and get no results. Anyone tried both brands that can give me advice on which one worked better.
