all worthless IMHO.
Four word .ORG - 1 to 2 many words for a .ORG
dash .ORG - dash is a killer
The "s" in toys for a net - does this one in.
The last one isn't bad - but not tied to a search term - a .net - sorry
good luck.
My suggestion, while .COMS can be used a brands even when not tied to a high search term - for .org and .net - they don't enjoy the same branding benefit as .COM. IMHO
