There have been some good research articles on arsenic and PT lumber. Most of the scares came about through the old CCA treated lumber. There are a couple new ways of treating lumber now, and they are supposed to be safer, but still there is leeching. Whether or not that leeching can hurt you is another matter. Personally I am leaning more towards concrete block as it's cheaper and can be made into more patterns more easily for me.

I've never used ties, but I have to admit I'm not scared of them anymore, either. Maybe it's from all of them I saw used around home, I don't know. I just have never had issue. I wouldn't use them now, but mainly because I can't move them around and I don't find them aesthetically pleasing.
I was using those "pressure treated landscape timbers" you see at lowe's and walmart. They only last a few years, they're really worthless. When I build my next beds, it'll be grade#1 4x4's.
Block would be cool, but you can't have anything around here unless you put in a footer. The ground would freeze the first year and expand and wreck anything you laid in. To use blocks, you'd have to use those fancy, expensive "block system" blocks, and that'd get crazy expensive.

I suppose it'd only be right to suggest to Matt to look into ties a little further and see what folks around him are using? If their livers are failing and their life spans are around 55 years, it might pay to lay plastic in behind them?
