low dose dnp is going to give you the most bang for you buck. it isnt going to hammer your heart and kidneys like other stimulate based fat burners do. again everyone says dnp is poison and is bad blah blah blah. well i learned from a pro that it does interfere with your training and how you feel when you push the dose up high and their is no need to crank it up to that level. 150-300mg and you will feel great and the fat will melt off.

as far as other choices:
prime nutrition backdraft xp (you have to cycle it because your body adjusts to the capsicums in it)
black lion incinderine (great burner with a bit of stim to it)
alphamine (i tried this stuff and love it)

my biggest suggestion for you if you are looking to go with a otc supplement would be to give tgb a call or shoot them an email. they wont steer you wrong and rip you off. the dude knows his stuff and doesnt put you on a product because it is the most expensive
