Hi Alex, i bought the 410 a while back and it was ok for what i needed it for 600x400x15mm Limestone, the blade isn't all that good it didn't leave a clean cut but my cuts were all hidden under the skirting so it was ok. its one of those bits of kit that i'll probably only use once in a while but it saved a lot of time and effort, i was tiling an ensuite in an attic conversion with no room for a table saw so i just used the 410 right outside the ensuite so no need to run up & down stairs all day long
TOP TIP i attatched the water pipe to a plastic petrol can and sat it on a ladder which gave a good enough "gravity fed" water flow, i also used a water spray bottle to wet the tile 1st because the water is fed to the rear of the blade and chucks up a bit of dust before the water feed hits it.
Sorry can't tell you any thing about the Makita.
