E-Stim and Cold Laser at home

Hey guys,

I am new the forum. I recently had my second ACL reconstruction about two weeks ago, both of them about 10 years apart. I started going to therapy this week to a therapist who specializes in athletes and sports oriented training. My last therapist only used E-Stim and now I recieve that and cold laser therapy. My new therapist encouraged me to buy an E-Stim machine so I could do it at home after I do my home-workouts.

My questions are:

1. Has anyone used E-Stim at home? if so which one?
2. Has anyone used Cold Laser Therapy at home? if so which one?

Both machines can get really expensive but you can find E-stims anywhere from $70 and up. The cold laser therapy machines start at approximately $400.

Thanks for any help that you guys can provide!!!

-the second sucks just like the first time!!
