What's my next option to clone 125khz card

I’m near Melbourne in Australia. I know there are a few people from Australia on here but not sure if anyone can help close by.

Initially I was hoping to write it onto a key fob just to check that it works and then once confirmed want to write it to an implant.

I was just hoping there might have been a cheaper option than a PM3. My other work uses MiFare classics and I can get by with my phone.

Is there a cheap reader/writer option that I can use with software to make this happen?

I also can’t remove the card from work and send it to anyone as it’s needed constantly.
