I went with Prosperion for my novated lease, and they've been great, even after I was made redundant and lost the novation. I'm now re-novating the lease with my new company. Along all the advice in the thread, my advice is to get all modifications added to the orginal invoice, as this is what is novated. Once you've got the car, its far more difficult to get any modifications made, as the lease companies usually don't want the value of the car to change significantly (either up or down). I even got my custom rego plates added to my original invoice, and thus the lease.
