I have to personally vouch for this suite of components. It is by far one of the best ones out there. Easy to work with and is not at all intrusive in your games, programs and other projects code. I am in the process of transfering all my DelphiX projects to XCESS. From the looks of it, it doesn't seem like that'll be a really hard transition. In fact it will allow me to do alot more that I could before. So thumbs up Harry Hunt! And everyone go checkout XCESS!

The site looks nice too.
