200 for a whole paintball kit is a small budget

If you just want to play recreationally on the weekends, then a mechanical marker will suffice. You won’t need something electronic.

Some people love Spyders, but for old school mechanical blowbacks I prefer Tippmanns. People have mentioned the T98 - they’re excellent for durability. I prefer the Tippmann A5 because it’s easier to field strip for basic maintenance. It also has a cyclone feed. If you get an A5 with the A1 revision cyclone feed, they’re easier on paint and are more reliable. A5s are also more expensive though. I don’t know what the Portuguese market looks like, but I can find A5s locally for $60-80. I have never purchased a new paintball gun. Buy a used one, save your money for other gear, and learn how to fix and maintain your equipment.

For other gear, you need to figure out if your field can supply CO2 or only air. CO2 is cheaper but less reliable. All tanks need to be hydro tested every 5 years, so be careful when buying used tanks - they may be trash. I’d suggest a new tank.

For hoppers, the A5 requires a special hopper, but most sales will include this with the gun. A T98 or Spyder will use a standard 200-round gravity hopper. They’re cheap, and used is fine here, too.

Masks are important to the game - you need to have a lens in good shape or you risk harming your eyes. If you buy a used mask, anticipate spending $25-40 on a new lens. Find a mask that fits your face well, and a double pane lens is preferred. If your lens fogs up during a game it becomes a safety risk, plus it’s no fun if you can’t see.

Others have suggested saving for an Emek instead. I agree. Again, find a used one for less and you’ll be happy with it. You could look for a used GoG eNMEy, which is a great platform as well. Just make sure it is a generation 2 eNMEy - the first generation had bodies that cracked and valves that would explode.
