Netspace do offer very similar services to iiNet. I suggest that you read the above threads, at least the first one before you purchase any ADSL hardware.
Netspace offers 512/128 flat-rate plans, along with other ISPs (you have to find one that suits you, not every plan is best for you, and I can only give recommendations and advice).
The Home 'Supa' and 'Mega' plans on Netspace's 512/128 connection are just as comparable to iiNets, offering 8GB peak traffic for the 'Supa' plans whilst the 'Mega' plans are offering 10GB peak, 10GB off-peak (for a total of 20GB per month quota).
* 512/128 connection
* Plenty of gigabytes of monthly data transfers
* Both plans come with a dynamic IP
* Upstream (uploads) are free.
* Fast Churn (rapid transfer) is supported
* PIPE access and Ausbone (for Netspace) is available
* 150GB of files are locally mirrored
* Access to 30 gaming servers, Netspace's FTP, Tucows mirror.
* 10MB of webspace
* 1 email address per account
* Peer to Peer traffic is free for users on PIPE, within the same state (NSW)
* Flat-rate plans available on Netspace, no excess charges
* IRC (AustNet) server available, free traffic.
* Gamespace and OGN gaming servers - free traffic.
iiNet do offer the same level of service, along with other useful (and free) services, including:
* Access to PIPE Networks - free
intrastate traffic on those ISPs connected to the PIPE. This means that you can send data and download from other users who are connected to the PIPE and this will not count towards your monthly quota.
* PIPE Networks' large FTP server for all your patches, linux isos, demos and other needs.
* Bit Torrent (BT) access, again, this is all free for those within the same state. (Get an IP filter and access to a tracker)
* Free IRC traffic for those on PIPE, through the AustNet's IRC server. You can stay on IRC and not have to worry about traffic going towards your monthly limit
* DC hubs, free traffic once again - users within the same state.
* eMule and eDonkey P2P servers - free traffic for those on PIPE.
* Plenty of FTP servers, including: iiNet, Internode, iPrimus, Pacific, TPG, Zip - includes all of your Tucows, Debian and Redhat mirrors eg movie trailers, linux, games, demos.
* Free traffic on game servers including Pacific, Persistent Gamer, Internode, iPrimus, HunterLink, iiNet, Comcen, BigBlue, supporting games like HL/CS, JK2, Q, Q2, Q3A, RTCW, UT, T2, NWN, BF1942.
Oh, and radio streaming from Nova 969 is free too! (Radio over the Internet)
* Plenty of genres: euro, trance, dance, jungle, classical, psychedelic, modern, alternative, rock, pop, metal, commercial radio.
