Confused (very easily done)

After looking and deciding we want an sr5 instead of the sr we will keep the prado for another year or two till we have enough $$ cash to update to SR5 hilux and get a new trailer instead, as we will need the space. I want to chip the prado 01 grande 1kz t/d, I spoke to the salesman at tuff truck on saturday for DP chip and while very helpfull Im still undecided between that and the Staunbauer. Besides the DP been made here any advantages or disadvantages. I was led to believe the DP had stopped production but obviously not. I have read many forums involving both these products, warranty, which one performs better etc, one saying it does more then the other then have read people have had trouble with both of them. Either way Im up for $1500 for either product. Some say I should go for the brand that goes before the factory computor others saying no go for the one that goes after the computer (witch both these products do). Now Im even more confused then I was before after reading up all day about them ??????? Too much reading I think. Only downfall is I wont be able to use in D4D when I do update. Regards Steve
