if your just looking to take wax off and not for any serious polishing there are a number of small cheap polishers that are great for this. they are not a super solid or heavy build and do not have a lot of torque but for wax it just is not needed. If you are going to want to do polishing then you will need to spend a few bucks and how much is up to you but its hard to get a good one for less than a $100. I have a porter cable and I was running a fan that I would set the polisher down in front of to cool it because the faster it goes and the harder you push the hotter it gets. I have a small one that I started off with that I would sell for $20 if it isn't a rip off. I need to check as I am not sure what it would go for as it was a gift a few years back.
