Hi all,
I think this is a great deal for a mechanical keyboard with doubleshot PBT keycaps. PBT is the hardest-wearing material that is commonly used to make keyboard keys (it is what was used on the original IBM Model M keyboards, if anyone remembers those). Doubleshot means that the keycaps are two bits of plastic molded together (the key, and the actual font on the key).
Considering you can spend over $100 for just a set of PBT keycaps by themselves, I think this is a good deal.
The cheapest option is with MX Black switches (linear and non-clicky), the other options are $20 more (still a good deal). Standard shipping for me is $9, but there are other options also (or you can pickup from Silverwater)
Probably the only negative with this keyboard is the font- might not be to everyone's tastes. Also, note that it is NOT backlit.

Edit: Just noticed that is has actually been this price before https://www.ozbargain.com.au/node/153073
Also I overstated the cost of the keycaps by themselves- looks like they have been as cheap as $29
Edit 2: Extra info from the store rep:
Vortex F-104 for $79/$59 for Cherry MX Black + postage
This is a basic but very durable mechanical keyboard. We recommend this for basic - typing - budget usage.
Deck Hassium (non-pro) for $109/$89 for Cherry MX Black + Postage
This is a backlit mechanical keyboard - also very durable, with multimedia shortcuts and software-free macros - yeah, the font is a bit 'interesting' but you can't really go past it at this price ;)
It's coming up as $79 for me? Would be a good deal either way.
