In my opinion, McMyAdmin is much better than Multicraft. I switched all of my clients to McMyAdmin and they couldn't have been happier.
are there any that are just a plugin, so i dont have to tear up my current system? (backups and gui's and what not)
You don't have to tear up your existing system to use MCMA, just drop it in the "Minecraft" folder and it'll just work.
