In SF I use Delancey Street movers. The experience has always been phenomenal. And they hire ex-cons who are trying to change their lives so it's win-win. Any tips that we give them is tax-deductible and goes towards programs for the employees and their families for outings, etc. Everyone works so hard, and they are extremely efficient, I have had no qualms giving 50% tips to these guys and I've used them 4 times now.
