The iPhone put me over the top with the number of chargers I would have to put into my travel bag, so I bought an iGo charger (with tip #: A61 Rev. 03) and it works pretty well. Best of all I don't feel like I'm damaging the port on the bottom of the iPhone. I tried a cheap 3-in-1 replacement charger and the power adapter wouldn't work with the OEM Apple USB cable, and the cable that came with the cheap set was VERY tight when attaching or removing it from the phone. The iGo tip was as smooth as the Apple connector and worked perfectly. I use a home AC iGo as my home charger now too - it's cheaper than an Apple charger and the cord is longer so I can use it while charging more easily.
