Nothing wrong with a $3 notched spreader. You're using a notched one, right? It gives a very even coverage with a notched one. Otherwise for wall tiles, using a small paint scraper (1-2" across) and sticking umpteen (definition of 'umpteen' varies with size of tile) even-sized even-spaced splots of glug on the back seems to work a treat. On floor tiles the notched spreader is essential or your tiles will break when you put something heavy on them.
I've done a reasonable amount of tiling - apparently I'm good at it and don't screw it up, but I'm the sort that used to make twiddly cardboard models and clay sculptures and things when I was younger and I think tiling falls in the same category of Stuff. The other half is hopeless at it, he lacks the finesse.
Tiling isn't that hard, the trick really is just to get a fairly even layer of whatever glug you're sticking it to the floor/wall with, otherwise you have to really mess around to get the tiles to sit flat. Too much and you get goo oozing out the sides, which messes with the next tile you put down. Oh, and use spacers. Spacers were invented for a reason.
Which reminds me, I have 40sqm of tiles, 20kg of grout and 9 bags of tile adhesive waiting for my attention on the front verandah. And a horribly uneven home-laid concrete floor to stick em to. I just have to evict a lot of furniture, a cat and two small children first ...
