Best weight loss shakes?

I had my second baby a year ago and I have a stubborn additional 10 pounds to lose, anyone have experience with meal replacement shakes that arent too expensive and are actually good for you?

My plan would be to just drink one for breakfast and have a salad for lunch and a healthy dinner, I walk 2 miles 3-4 times per week, but that's about all the exercising I do (besides chasing around my 1 and 2 year old)

I'm 5' 7" and 147 pounds, 137 is my pre baby weight, ideal weight is probably low 130s

Thanks all!
