I used Cardinal Moving Systems with my last move. I researched quite a few companies before going with Cardinal. The reasons that set them apart from the others:
1. They were very prompt with my request for a quote. Once I received a quote, they didn't badger me like some other places on if I made a decision yet. That drove me nuts when I would get email upon email after just receiving the quote.
2. They were very informative and gave me honest answers. They even gave me advice on some things I didn't even think of (and I've moved quite a bit)
3. They didn't break anything! I've had horrible experiences with movers before breaking stuff and tossing my valuables around like they were footballs. The guys even showed up a little early, which I didn't mind at all. They moved pretty quick and got my entire apartment packed up in less time than expected.
I really hate moving, but if and when I do move again, I will be using Cardinal Moving Systems.
