UML Modelling Software Recommendations

Hi,

Im looking to invest in some UML modelling software before I start my last year at uni.
At the moment this is mainly to save me from hacking together diagrams in visio but ideally I would like a fully featured product that will be of good use after I finish uni.

What are your recommendations? Im happy to pay for the software but I dont have thousands so that rules out any IBM Rational stuff.

I've had a look at Sparx Systems Enterprise Architect which seems to be my favourite at the moment.

Thanks.
