The Elf has raved about his Roland Dimension D hardware chorus on numerous occasions, as it provides subtle but wonderful stereo enhancement and movement without obvious chorus swirling.
I've just heard that the excellent Dimension D plug-in developed by ERS (along with the other two plug-ins in the ERS range) have been taken on by DDMF (developer of the famous PluginDoctor along many others), and as a special introductory offer they have knocked 50% off their prices until March 1st.

Be quick and download the demo if you want to take advantage of this offer!
Suffice it to say that I've just bought Dimension D from DDMF for £17.50+VAT= £21.00, and I'm extremely impressed.
