Carrierwave vs paperclip vs attachment_fu ??

I need to upload not only images but also other files(excel, pdf's),

I would like to setup custom validations for the specific file uploaded(size, format) and I am using rails 3

Any recommendations would be greatly appreciated.

Thanks

Go on with carrier wave. According to Rails cast it works perfectly on Rails 3. See: #253 CarrierWave File Uploads - RailsCasts
