The OP is my hero. While I bet this thread is going to go off the rails in record time, I actually think this is a legit topic because I'm in a similar spot.
My $0.02 is that if you think you'd be happy with the SW pro then go that route. You'll be keeping a lot of powder dry and can pick up a DI on the secondary market down the road (I've actually already seen one for sale). To me, it's a much tougher question if you feel like you'd want the SW pre or LE vs. a DI because then your costs are pretty comparable.
Whatever you do, I bet you'll be happy with your choice. Good luck.
