My first computer was a C64 also. It cost A$699, plus $99 for the tape drive. In 1982 money. My father's salary was about $40,000 per year then. Can't think of money better spent.
We had to go on a waiting list in Norway to get ours because Commodore had a hard time ramping up to meet demand and so availability depended a lot on market. Probably went on the waiting list end of 1982, and got it spring of '83. Until then we'd been borrowing a VIC-20 for some time.
