ORM for CodeIgniter -- DataMapper? Eloquent?

[eluser]coderego[/eluser]
It has been recommended to me to use Eloquent as an ORM for CI. I have encountered a good amount of errors with this. Most I have since resolved, but it does seem a bit awkward.

Does DataMappper have all the features that Eloquent does? The website seems to indicate that it is not actively being maintained...in fact I'm not even sure if it is usable with the current version of CI. Is it?

THanks!
