If you already have cordless tools.....stick with that brand. There is not enough difference between the major brands to jusitfy trying to maintain 2 battery platforms. If you really think this is going to be your only use of a sander, rent one. If you want to buy one, a corded one will be much cheaper than a cordless one. If you want to go cordless think about the other tools that the company offers. You won't be buying just one tool...you will be comitting to an entire tool family. Eventually you will end up with a drill....an impact driver.....a few saws.....etc. Spend a little time on Youtube and you can see lots of reviews and comparisons. I am partial to Milwaukee because I think their battery technology is superior but the differences are probably not very significant. Don't forget that you can rent a sander from Home Depot if you are hesitant to buy one.
