$72.99 plus shipping. As it is shipped and sold by Amazon, if you add another item to your cart to reach US$100 you can still get another 15% off with Amex https://www.ozbargain.com.au/node/213540?page=1#comment-3127… which brings the price down even more on the Tascam.
The lowest price this has ever been was US$69.31 but I waited too long and it jumped up. I just got a camelcamelcamel notice that it dropped down again. If you are a Prime member, it is even cheaper, it says it is US$70.03 for prime however for me the Amazon website says US$72.99
Cheapest price in Australia with Aussie warranty is $129: http://www.dwidigitalcameras.com.au/astore/Tascam-DR-05-Port…
Also consider, some Tascam devices have bad reviews regarding build quality, this is a quality control thing so this could be an issue if you purchase from Amazon because you cannot send it back as easily as a US buyer.
Accessories that I suggest from my research:
This dead cat/windscreen: https://www.amazon.com/gp/product/B00HX40OL6/ref=ox_sc_sfl_t…
This is the best Lavalier microphone under $50: https://www.amazon.com/gp/product/B009YCI62Y/ref=ox_sc_sfl_t…
Windscreen for Lav mic: https://www.amazon.com/gp/product/B005LR0ETO/ref=ox_sc_sfl_t…

Oh and btw, the reviews I have seen say this is better than the Zoom H1. Bigger, but better. There is also a newer DR-22WL which is more expensive and has wifi, I also missed buying it before the price jumped, however the wifi app is not that great, it does not allow you to listen live.
