Best Shotgun for Trap/Skeet?

In My Humble Opinion
1

What is the best gun for trap/skeet shooting? What about sporting clays?

Will one gun suffice for both styles of shooting?

Purchase Source: Will a WalMart gun (Remington) do the sport justice? (about $260) Or, do you really need to go to a sporting good store or gun store for better service/quality?

Semi Auto, Over/Under, Side-by-side, or Pump action?

What about favorite brands? Remington, Beretta, Mossberg, etc.

Should I get any choke tubes to use? (BTW, I don’t know anything about choke tubes. I was going out to buy a shotgun for trap shooting and got confused. I bailed out and came here for advice.)

Thanks in advance.

Well, a lot of Olympic shooters use Perazzis, but I hear they go for around 7large. I met a guy recently who uses a Krieghoff. Also not cheap. Way outta my league, for sure.
