Esprit or Elise or Exige

Hey fellow automotive people.

I was driving one day and saw a brand new lotus elise... my jaw droped. So, i started looking at Lotuses. I can decide!
Is the Esprit worth the extra $30,000 from an Elise.
And what is the differance between an Exige and an Elise.

I would greatly apreaciate some stats mabey and some advice.
