Yep, more parts means less reliability, especially with adding LPRs. However, the only thing that has, err, given up on my EP classic is the quad o-rings I put in it. I went back and tuned it with a regular o-ring. A palmers micro rock has been well behaved, which helps the solenoid valve. I think if you get it set up right and use loctite right, they do alright, especially for the higher rate of fire that they usually end up with.
There's a good pneu thread in the stickies above. You have to plan out your air lines on a pneu, it can make a difference in cost and operation. You get into the valves and ram, but the air line routing can get left to the end and cause trouble.
