If u are talking about Bosch GEX 125-1 A/AE polisher, I have an old one that I'm about to throw away or donate. To be honest, after using longer throw DA machines, Bosch DA throw seems to be the lowest, 1.25mm throw only, so it does very little in terms of compounding or polishing.

If u want u can have mine, but u have pay for delivery (if cannot collect from Wangsa Maju), and u need to get a new backing plate for it because my current one the backing plate velcro no more grippy.

I not sure what Osren DAP3 specifications are going to be like, I think it could be a forced rotation DA machine.

If u are on a fairly tight budget, then perhaps u can consider a vertical rotary polisher instead. While I generally dont recommend rotary polishers to newbies, however given that u could be on a tight budget, a typical Skil vertical rotary polisher would only cost RM200 (pads sold separately, u may need to find Osren for that). U may face a steeper learning curve with a rotary polisher, but good polishing results can still be achieved. Something for u to consider.
