Regarding machines, I have an old Vitamix 3600. This thing is like an old tank! It's from the 60's and weighs a ton.
I personally try to buy organic where available, but if for whatever reason (quality, availability, price, etc.) I can't, I'm still cool to use conventional. Yes, there are GMOs and chemicals. But one must remember, most of the major research done in the past regarding the benefits of plant based diets were NOT done with organic foods.
Organic or not, it's better than no veggies at all.
