not to knock on keyclone's programmer, but i prefer innerpace. Keyclone is good but a little too basic, but easier to setup.

when you first start using isboxer/innerpsace, it could be a little daunting getting everything setup right. But there was an update to isboxer that has a setup wizard, so you can easily setup stuff and just start playing .. I really enjoy the macro making part of innerspace and using advanced macros is great. If you are interested check out zanthor's guide at

also if you plan on buying some time for innerspace, use the refferal in that post, I am sure zanthor will appriciate it

they are similar in the sense that can broadcast keystrokes to all wow windows, but i think that is the only similarities(other then a few options each have)

I would say just go to the website http://www.lavishsoft.com/joomla/ and look at the wiki and or watch the youtube videos. this way you can see innserpace/isboxer in action
