I use the GNC Beyond Raw Ravage pre-workout cause it was on sale last time I went to buy my protein powder and it contains almost all of the ingredients listed in this article. It's cheaper than other pre-workouts because it's the generic brand but I really enjoy it. I've only ever had the Hawaiian Punch flavour but I'd mix it one scoop with a scoop of the strawberry ON Gold Standard Whey and it tasted delicious as my pre/during workout shake.

Musclepharm assault is actually not on this list but I have done well with it.

GNC Beyond Raw got garbaged. Spent more time fighting my stomach between sets than actual work. This list is heavily skewed. I've been taking MUSCLEPRIME by Allmax and it isn't NEARLY as heavily stimmed as some of these, and you still get quality energy.
