Just happened to be in the market for a new budget condenser mic and this seems to come highly recommended.
There is a cheaper one on Amazon but this particular listing is fulfilled by Amazon Au.
Not historical cheapest but seems to be going for about $129 elsewhere currently so seems decent if you need one now.
Please note this is an XLR mic so you'll need some sort of interface with your PC if you're planning to connect it. I'm currently eyeing off a Focusrite Scarlett 2i2 (if anyone has first hand experience with one also keen to hear about this)
