A couple notes regarding pipe cutters. If you get one, get a decent one. I have one that I used to cut a steerer tube and handlebars and that's about as far as it got before massive chunks came out of the blade. Also, be light-handed and careful using one to cut aluminum bars - it is a lot easier than you think to ovalise the end that you just cut. Finally, if you do ovalize the end of your bars, fix it before you jam a bar-end lever in there or you will NEVER get it out again without about 90 min of work, some spilt blood, and a lot of swearing.
