If FR are the only airline that fly that route and you're staying near STN, then it looks like you don't have a lot of choice! As long as you know the rules of the game, it'll most likely be fine. I'm absolutely no fan of FR, but I occasionally fly them and try not to check in luggage when I do. A couple of months ago I flew STN-TMP with checked luggage, and all went smoothly - 10 min bag drop queue at STN, and bags arriving at belt in TMP before I got through passports. When it's OK it's OK.....
