I'd follow what The Infected said about the Phantoms
Congrats on your first pump and/or paintball marker!
Keep note of how versatile the platform is and you can really upgrade the things to infinity! Best of luck and hope you enjoy it.
Some suggestions if you ever do want to upgrade would be to invest in a cocker threaded breech and an undercocking kit of some (good quality) type.
With a cocker threaded breech, you have the option to run a plethora of high quality and small bore barrels that aren't available in phantom threading, and this can let you cut down on the amount of parts you need on the gun (like those detent rings or other small widgets and what have you).
