tysfoot mate, the master
tiler will cover you for near enough most jobs really, and it's a good price, but for smaller jobs I use the smallest Plasplug wetsaw, forgot the name, only £30 but it has done brilliantly for me, as some bathrooms are just too small to have the Master
tiler in there "in my opinion"
Where as my small cutter can be easily moved over and over as Im working, it can fit down the side of the wall and toilet while moving things around, where you can't do this with a Master
tiler, it's just little things like this that makes having a smaller wetcutter an advantage for the smaller jobs.
Though some people won't be bothered about this and might have the cutter outside or in another room etc etc.
