What to do?

If you can do majority of the work yourself, go for it. If not, consider labor, parts, and the whole nine that has to be done in order to make it a solid roller. You mentioned that your car needs a ton of work... I would stay focused on that. You never know what tomorrow holds (I've been down that road). You can purchase the Duster and hold of until you're ready for it, but it's all up to you and how your pockets are set.
