Caffeine Free Focus XT is money - as far as effects, taste (which is absolutely wonderful), and price point go. I wouldn't hesitate to recommend it.
Combining Caffeine Free Focus XT with iForce Hemavol (for the pumps and endurance) and Compete (which, if you're lucky, you can get for free - this product has some great recovery, endurance, and extra MOAs for mental enhancement and focus) is something that I absolutely love doing when I'm trying to avoid stims. It almost makes me not miss my beloved 1,3 DMAA and caffeine.
