Blimey thats an expensive tile cutter! You got a lot more tiling to do? 60cm tiles? IMO the gear for tiling goes up exponentially vs the size of the tiles your cutting.
When I was last tiling I was using 60x10cm plank effect tiles so a cheap snapper was fine for the cross cuts.
The length cuts I just did with my £50 wet diamond tile cutter. It was only a few meters worth.
100% agree with the dry cutting/laying approach. I did this and found it easier. Then just wack a load of adhesive down and lay tiles, more adhesive, more tiles etc until done.
All looking good, bet your chuffed
