Start-up aid to the machine polish

Hello together, ( ) after having been helped so excellently here to get into the topic of car maintenance (washing, sealing, etc.; and defect removal by hand), I would like to ask for your help again, since I would like to finally venture to the machine polish. The whole has still until spring time, but I would like to find the appropriate components. I have already read a lot about it (FAQ, blogs, many threads). I get together what I experience in Erfahren. I don’t want to throw money out of the window, but in general my budget for everything is quite high: (if it has to be) I’ve taken 3 in the narrow selection so far, but I’ve seen that there are lots of others that are often recommended (Krauss, Hofftech=Dino power pack with shorter cable, DAP, …), many of which are identical. Otherwise, of course, I need some extra accessories. For polishing I already have: Sorry, this is jetz But as you can see, I have already tried very hard to deal with the matter and I hope for your active support and help. Greetings, Marius
