As said it before, there are seller on ebay and amibay who sells SwinSID, built, programmed .... i doubt they have any more permissions to do so.
ReSID-fp is only the foundation and not the source!! The code Hermit wrote is 100% avr assmebly, with tricks and shortcuts to be able to handle the task in this puny uC (mostly the comments in resid-fp has been used)
My device has a lot more components, needed a lot more time to even laid out the PCB, so for assembly alone would grant it's price!
But as I said, how would you blame the clone sellers that they "steal" something which is freely available, if your approach isn't better?
Maybe because after long years of no progress, Hermit and I have increased the compatibility and quality to an unimaginable level? We did WORK on this (not just cosmetic)?
They can sell whatever they want but I would like to get something back for my work too.
And for hobby builders -- can you really put two QFN16, an SOP8, a TQFP44, a TQFP32 a dozen of resistors and half a dozen capacitor to a PCB the size of a DIP28; program a Xilinx CPLD and two AVR uC ?
Not to mention, if you could design and make your own PCB...
And for last -- even IF the Atmega code is not clean, the CPLD and the Attiny(paddle) are, and w/o those, the Atmega can't work properly...
Also look at how many products has gone from open source to closed -- not only to hide from hobbyist but to protect themselves from cheap knock-offs or because the complexity is now beyond the average hobby builders.
The code is not completely blocked off from people, because Hermit made the jsSID based on the code he written for the SwinSID Ultimate: http://csdb.dk/release/?id=145523
