I do not want to be annying but some times you can find good things at low cost, but because money is my limit I dont want to spend on something bad..
You should do as you choose but I'll add this...
I've tested a lot of low-end free-spinning orbital polishers, basically knock offs of something like the Porter Cable or a variation. Most of the time, while they can look like something that works, where they miss the mark is the ability to rotate a pad under pressure, even a little pressure when it comes to curves.
If the pad on any free spinning orbital polisher is not rotating and oscillating, then you're not doing any work.
The definition of the word work in this context means to remove a little paint as that's how you remove defects. You don't actually remove swirls, scratches and water spots, you level the surface until the surface is level with the lowest depths of the defects you're trying to remove.
On Tuesday, I used each one of the polishers you see in the pictures below, these are brands Autogeek carries and while some ore more effective at maintaining pad rotation than others, they can all get the job done, that is they will all rotate a pad and for the most part, maintain pad rotation with some level of pressure. (Long stroke orbitals don't require much pressure but short stroke polishers work best with some pressure).
Out of all the polishers shown, in my opinion, the best bang for the buck while keeping your tool dollar investment to a minimum is the Griot's Garage 6" DA Polisher. It's what I call an entry level or beginner's polisher but with great products, the right pads and good technique you can tackle just about anything and the warranty from Griot's is hard to beat. You actually don't see a lot of threads with "issues" surrounding any of these polishers in the context of how many we sell or are sold on the market and that's a sign of quality.
Of course, the large polisher that looks like a steering wheels is not really included in anything I wrote above, it's from my antique wax and polisher collection.
