What do you actually want to use the HardSID for? If it is just to playback SID music using a real chip with ACID 64 or a similar program then have you also thought about getting a Catweasel MK4 instead? This also has support for a SID chip onboard and the programs including ACID 64 support it too. Plus you would gain the floppy controller, as well as the Amiga joystick/mouse ports and keyboard port.
