True!
Cockers are nor as user friendly as something like an automag, or especially things like spyders or piranhas.
The reason I say that I would prefer them over mags is this: When the mag was first released it was state of the art. The fastest marker around! One thing they lacked compared to a cocker was accuracy, but they made up for that by the volume of paint they flung. Nowadays the mag has been overtaken in the rate of fire race. Electroes will outshoot a mag any given day. Most of them will also be (somewhat) more accurate. The cocker has always adapted to new developments. And what's more, they are very easily upgradeable, and for a reasonable price too. Okay, you can fork out the cash for a seriously pimped out one, but you will be paying for cosmetics as well in that case, and I'm not sure that's what you're after judging from your post.
There are mags out there that are more adapted to be state of the art, such as the RT and the e-mag, but they are consequently more expensive.
As far as electronics breaking down, I've never seen it happen (doesn't mean it doesn't happen ofcourse). The electronic markers mostly suffer from the same things that other markers suffer from, i.e. o-rings going fubar.
You asked for my advise on markers, that's what I gave you. If you want my advice on how to get started, it's this:
Try out paintballing first. Don't spend a heap of cash on a hobby that you're not sure you'll be doing for years on end. After all, you never know. In this context, the standard automag is an excellent choice. An easily maintanable marker, that can easily be upgraded to more or less tournament standards. Sure you'll be outshot by teams brandishing Angels and things like Eclipse/Freeflow/Whatever cockers, but then again, it's all a case of picking which tourney to play. If you can do so, sign in as a novice team, which will mean that you'll be playing teams with more or less similar equipment and skills/experience. If the tourney uses a seeding system, chances are you'll get shot to bits by some pro/top am teams in the prelims, but you learn a lot from that, and you'll be playing teams of a stature equal to your own once the prelims are over.
Anyway, good luck, and I hope you manage to get a team going.
