The version of head-to-toe, and if possible, piece by piece, including forearms guards, I think the hoplon aspis costed 200 drachma? What about the helmet, the spear, thigh-guards, dagger, sword, and what about the differences between what kind of spear could afford the wealthiest and the poorest hoplites? I know the poor ones could only afford shield and spear, perhaps helmet, and be glad with them.
Well, summing up, what was the cost, piece by piece, of pan-oplon, that is, a panoply (full equipment)?
Unfortunately, this question is unanswerable, at least at the level of detail you're asking for. Some of the pieces of equipment you're mentioning were only in vogue in the period before coinage was widely adopted, meaning that no monetary value was ever expressed for them. In most other cases, prices are only known by inference and estimate. For the aspis (this shield is absolutely not called hoplon, regardless of what Diodoros and countless misguided modern authors might tell you), the only known price is 20 drachmai, but it's not clear how widely it might vary; a scene from Aristophanes' Peace suggests that the price of weaponry would radically increase in wartime and decrease in peacetime. The price of a full panoply can only be very roughly estimated; such estimates usually fall somewhere in the range of 50-100 drachmai.
And how would those costs compare to the best estimates of the buying power of that money, or to a day's wage for an unskilled worker or a skilled craftsman?
