Purely SEO wise: A .net is best in your case.
For ranking in the SERPS, .net or .com doesn't matter. Even a .org would be fine.
.info, .biz are a little tricky, since many spammers use them because they are cheap, google seems to have less tolerance towards shit on a .info than on a .com, .net or .org.
I personally hate dashes since they only have disadvantages (key1-key2.com will often only rank well for a "key1 key2" search, while key1key2.com will rank well for "key1key2" and "key1 key2" searches).
So, dashes can make sense for search terms naturally searched with a space between them, but they don't have any advantages over non-dash domains, well, sometimes it looks better and is easier to read, but not SEO wise.
