Pretty good price on the S2 which is getting a bit old but is still a great phone. The "Plus" refers to it having Jelly Bean pre-installed, which gives it pretty much the same UI and features as the S3, but in a more compact form which some people may prefer. Please note the Plus model has only 8GB internal storage vs 16GB on the regular SII. Ships in 3-5 business days according to their website.
I personally have not shopped from Value Basket before so can't give you any feedback. If anyone else has experience with them please share with fellow Ozbargainers.
EDIT: Just saw the Galaxy SII (16GB) is $288 shipped from Kogan, so that is probably a better deal, as you can upgrade to Jelly Bean via Samsung Kies software on your PC.
