At level 15 you really don't need to worry about it. Most mods will give bonuses to skills you can't even get yet. As far as the Pointman mod, that's actually one of the worst mods for a Commando to use as he levels because it gives a static bonus to Health and Regen. As you level up it will help less and less. There's no good place to farm for mods since they are random. Keep looking and you'll find some as you level.
A good Tactician, Veteran, or Rifleman mod will probably serve you best in Playthrough 1. Just pick whatever looks good though, and don't be afraid to try out new things. --- The original
To each their own but I actually find Pointman invaluable. I'm not saying no to health regen and just swap mods as situations see fit. I come across better versions of Pointman every couple of levels so it's not as if I hang onto the lowest bonuses forever. --- It's raining luggage and babies and limbs and Daddy doesn't come home.
