In reply to LP:
I don't rate a pegboard at all. You can train lock offs at far more climbing specific joint angles with other equipment, assuming you aren't training for winter climbing.
Things I would prioritise before building a pegboard:
1) A good fingerboard setup with pulley system to remove weight and weights to add weight.
2) A steep board (40-50°)
3) A less steep board (15-30°) for endurance work
4) Rings or a TRX
5) Basic weights / dumbbells for core workouts, antagonist work and injury prevention
6) Pull up bar
7) A campus board
8) Micro crimps (see 1 above), a pinch block and mono trainers
9) Barbell for deadlifts and a bench for benchpress etc
10) Parallettes and an ab rollout wheel
11) A sloper rail
12) A crack den (and I don't even do crack climbs!)
Etc etc. Basically, a peg board would be so low on the list of priorities that I would need a near infinite amount of space, funds, time and energy before I would consider installing one.
We have one at our local wall. Gym rats play about on it before returning to campussing their way up V1s. I don't think I've ever really seen anyone doing any form of effective training on it.
