Might want to consider Olympic and CRIS, never for baseball, there are better options but great for football and these two are safer than most and first out with lines. Another very safe book not mentioned is WSEX, these three along with Pinnacle are IMO the safest of all the unregulated books.
On your list I would agree that probably Pinnacle, BetJM and 5Dimes are the best, might want to look into the exchanges as well. Good luck.
