I'm sure you can find one on Ebay
For a price tho... and also here in Australia I can still purchase SNES, Sega Megadrive and other older consoles... some people are actually getting rid of them... the loonies they are
But in regards to the C64, hmmm... been a lot of years since I fiddled with them, but I do recall that you encountered that problem with more than 1 drive connected on start up. But then that was the old C64... there were 2 or 3 models made back then... latest one was slim and looked a bit like a mini amiga
