I've been using Ashampoo burning studio free for a few years now, but today only at giveawayoftheday.com, they are giving away Ashampoo Burning Studio 2010. The app must be downloaded and registered TODAY to get it for free.
This app is easily comparable to Nero (not quite as good, but free!) and in my experience of using the free versions, creates far fewer coasters than InfraRecorder and CDBurnerXP (I've been using it on a mac and a PC for over 2 years now). This is also known as Ashampoo Burning Studio 9 Advanced.
The deals usually finish at 8am, so it will be around on the 27/08 for a bit.
