The creators just share a great program for free.
They have published plans to build interfaces for around ŭ.00.
Others have listed interfaces here for around บ.00.
Some have friends that built them at cheap prices.
E-Bay cost vary according to supply and demand. I have seen them go for less than ŭ.00 to more than you paid.
If you think about it, if they were making interfaces for other, buying the parts, spending time researching what needs to be done, spending time building the parts, taking a chance that they could sell all they built, and then advertising them.... อ,95 is not a bad price for them. Remember the after marked support, and cost of replacing interfaces that don't work right.....
All in all, it would be nice to get the interfaces for ŭ.00 or less, but you would have to find someone willing to do all that work for that price.
The other brand of simulator goes for around 赨.00 so the อ.00 is realy cheap on the comericial market.
I help my friends with building them. It feels good to help them. But as a full time buisness I would loose my shirt.
Just one man's thoughts on the subject.
