Get high repair early on. It will help a bundle during the whole game. If you use the same gun or armor as enemies then you will never have to pay to get your stuff fixed. I would also recomend wearing the Ranger battle armor if you find it because this can be repaired with the Talon company armor. If not a power armor will also do but I just don't like them.
I also recomend that you learn to use small guns. The hunting rifle is strong when you know how to use it and it is a very common weapon so with high repair you will always keep it good quality. Also the special rifles such as the Lincolns repeater and Ol' painless get repaired with ordinary rifles so they stay good quality and with a high level in small guns they pack on hell of a punch. Same thing with the Terrible shotgun.
