Recommended actions for super low stim/non stim pre-work out on a budget ($40)

As title suggests. I really can't justify spending anymore than $40-45 USD for a super low stim non stim combo. I have plenty of high stim pwo. I was looking at htp off the chain and n.o. overload. That might be around my budget mark. I really don't want to mix powders for that. Would those two be more ideal? Maybe throw in some beetroot? Off the chain is around 220 mg of caffeine and prefer it to be slightly less. Any suggestions or recommendations? Thanks!
