I know what you guys are saying about certain tiles at Home Idol. The ones I ended up getting from there were individually cut and are dead straight. With this style, it's really easy to tell if the tiles aren't perfect (12x24, no real texture, flat, 1/32 bevel). No issues installing or cutting them, other than working around imperfections in the floor. I didn't waste 1 tile of the 49 I used and none of them were broken in the package.
I used random staggered, glass and marble mosaic sheets (cut into 1/3rds) as an accent in my tub stall and a lot of them weren't straight or were broken and needed to be cut out and replaced. So it can be hit or miss, depending on what you buy.
