I'd go for Chicago-Latrobe, Triumph, Precision Twist Drill, Cleveland, to name a couple.
Biggest two things IMO are: use a stationary tool (a drill press or mill) whenever possible, and don't run them at 80 bazillion rpms. 500 rpms is plenty for a 1/8" drill bit, go down from there as size increases. The edges will last a lot longer.
