I went through a bunch of editors trying to find one that my clients couldn't screw up. All the high rated free ones, the pay ones...None of them really seemed to work the way they were supposed to in all situations or things were missing. This one just works right.

It's a little cryptic to customize (but really not that bad) and the support is very quick to answer questions and provide information.

Lots of buttons can be added on the tool bar and it can be customized to fit in fairly narrow spaces.

I was hesitant about paying for an editor at first, but it's worth it. I wish I could have all those hours I wasted on other editors back.

This is a very stable product Its just slow. Now I'm not sure if its their server or my computer was just randomly slow (and I doubt that) but the demo seemed to lag a lot. I didn't use the demo to much because I was getting frustrated with it. The tool bar could also use a little more organization and slightly bigger pictures.

Tried several other WYSIWYG editors and found Asbru to be a nice solution for the Safari browser. Easy install, easy use, nice feature set.

I'd always prefer JCE. JCE is just more beautiful an incredibly powerful, especially with it's Advanced Links plugin.
This one claims to be "From only £25 per website with any number of users" which equals to 45 Dollars or 37 Euros.
If I remember correctly, JCE is only £0 (do the currency conversion on your own) for an unlimited number of websites.
