I think that there is a lot more than just the actual manufacturing cost that goes into pricing a product. While in terms of materials and labour to build an Oasys 88 it is probably quite low now compared to the actual selling price, there is the R&D costs of originally developing the hardware and software plus the ongoing software cost to upgrade it with either new features and bug fixes.
I won't pretend to know what it actually costs to manufacturer an Oasys but there are a few things that go into my decisions on whether to buy a piece of gear or not. How badly do I need it, will it make my life easier/better, can I afford it and do I feel it is worth the asking price (to me)?
dhjdhj: I rarely consider the resale price of a piece that I buy. When I buy, I look at how much use I will get out of it and whether it will make me money (or make me happy

Anyway, not trying to cause waves here so I hope that I'm not offending anyone. Just thought I'd put a different perspective on things.
