You have to consider one thing... skis are put together but low qualified work force, not by rocket scientists with big salaries. With Elan (which HQ and main production factory is about 30km from me... in same country), average month salary of people in production (race service or normal production line doesn't really differ much, if at all) is around 600-700eur/month... neto. With current taxes etc. brutto is around 1500eur/month max, probably less. Around here, average monthly sum of hours is around 160, which brings approximately 10eur/hour brutto rate, most likely even few % less. And that's how much labor costs company. You are mixing what store/service is charging you as client for their work, and expenses which company/store/service actually pays to their workers ;)
Anyway... this data about 70eur/pair is not for Elan, but it comes from some other (in race world much higher ranked company), and it comes from reliable source, who is with this company for years and he has enough of overview to their operations, so I'm pretty sure it was right... even though it was quite surprising when I heard it. Another thing is, low end skis, sold for 100 200 or 300eur, are not much cheaper when it comes to production costs, then top models or even race stock skis. So here's another info that really surprised me. Most of revenues are made with race skis, which based on previous information is quite logical... You get cheap skis made for maybe 20% less money, and with top skis you get I don't know, maybe 500% more money when sold (normal price for high(er) class skis here around are 700-1000eur/pair). So even if you sell less, you still get more money in.
Checkracer... salaries in production (or in general) are not all that much higher in Austria as they are in Slovenia. Sure they are some 20% more, but that's not all that much more. But to be honest, I have no idea how's current situation in Czech or Slovakia, so I can't say anything about this.
