A question

If any of you out there in Journal-Reading Land have had experiences with professional movers, I'd like to hear about them--particularly for recommendations or people to avoid, and any tips. This has become the biggest source of anxiety about my upcoming move, I'm realizing. Kitana's correct in observing that worrying about it doesn't do any good in itself, but I'd nonetheless like to try to keep the odds in my favor for getting a move that begins and ends smoothly without hidden extra costs.
