Hi Farkas,
He, he, pity is though... the major shops here in Germany are taking a break from Pittsburgh Modular. In 2019 there were still dealers to be found where one could buy Pittsburgh Modular, however since last year most of those shops are putting an end to Pittsburgh Modular. There is here one shop left but that one doesn't carry at the moment the EP-420, so I don't have any price of that one. Oh and I found another shop but they also don't have the EP-420.
Now luckily I wrote down back in 2019 the prices of cases because I was comparing them at that time to see which one I should buy so I rely here on an old price (I will take the cheapest, I had two prices) for the EP-420 that was Euro 889 somewhere in 2019.
EP-420 is 3 rows if I remember well, each row 140 HP, so a total of indeed as the EP indicates 420 HP :-) That would make it Euro 889 / 420 = Euro 2.12/HP, ehm... Farkas...? That would make it the most expensive one of the whole lot ;-)
Of course, I agree, from an aesthetics point of view, those low costs cases from Doepfer don't look very fancy but if we just talk about a plain & cheap case, there is nothing cheaper (and quite good actually) than a Doepfer low cost case, being it the 84 HP series A-100LC6, LCB or LC9 or the 168 HP series A-100LMS9 (or LMB).
Kind regards, Garfield.
