Competitive is a very relative term. I've interacted with teams that consistently medal at nationals, and treat SO as a year round, varsity level sports, as well as teams at the other end of the spectrum that can't pull together 15 competitors and start looking seriously at the rules just a few weeks prior to the regional competition.
While a stock arm won't be competitive at the national level, for the majority of the regional tournaments and teams it would be more than sufficient to allow them to compete at a reasonable level.
The one I was referring to on Amazon.com (search for "OWI Robotic Arm Edge") costs $37.43 with free shipping. It has a reach of 12.6 inches (~32cm) and lifting capacity of 100g. By my calculations, the arm only needs to reach ~30cm to get to the front edge of the east and west goals. I can't speak to how fast it moves, but the bottom line is that out of the box it would be capable of getting more than half the points in the event, which in my opinion could be considered a competitive, cost effective option for the majority of the something like 6000 teams that compete each year in SO.

By my calculations the edge of the field at the midline is about 47 cm away from the center of the robot square, so allowing about 12 cm for the goal that is 35 cm to the nearest point. If the base of the robot is small you could maybe move it a little closer, but only towards the midline - if you move it towards one goal you move it away from the other, and the north goal and bonus box would be completely out of reach. One partial solution would be to allow the arm to travel within the robot box, instead of requiring a stationary base. This would allow teams to mount their arm on a very simple chassis (which could be a cheap RC car for another $10) and at least be able to hit the two near goals.
