Variety is the spice of life.:) I love my SV machine. Fantastic for fish, scallops, making yogurt, creme brule, warming up leftovers, SV eggs(if you get it right) are out of this world. I would do without the microwave in a heart beat but not the SV, no comparison. As Jon mentioned it is great for doing boneless skinless chicken breasts, so little effort needed and a lot more flexible on the timing, if you run over the time, no big deal.
Like any new tool one needs to work at it and learn how best it works for what you want to do.
