Cross-country move, moving pod comparisons?

Hey all, I'm going to be moving from Seattle to Boston for graduate school and I'm looking for a second opinion. I was planning on using Uhaul's U-Boxes to move about a studio apartment's worth of stuff, and just wanted to check that this would be a good idea. I've looked at PODS and the U-Pack ReloCubes, but they were both a good deal more expensive than U-Haul. Should I spring the extra $500+ for one of these instead, or will I be okay with U-Haul?
