I have a brand new, never used service manual for the LX 125-150ie. I think it is a bound copy of the online version but it looks comprehensive. It is in English. (See photos)

I always prefer a paper service manual as it is easier for me than flipping/searching screens on a laptop or tablet.

I paid $27 on eBay but will sell it and ship it to the continental US for $20. Outside the US I will have to calculate actual shipping costs.
