Yes, Profili is good. Something you didn't point out is that it works as a basic plotting and modifying tool for FREE. The payment of the paltry $10 let's you unlock the advanced features that are well worth the price.

But I've been lazy and have yet to get the unlock code from him ....

Anyway, another great tool is Tracfoil. I find that the slight differences in the utilities makes having them both worthwhile. And, once again being lazy, I still have to register for the $20 US (IIRC) and open up my trial version.
