I don’t typically see people advocate for the cheapest gear, just not to go all-in. There is something to be said for how much you can learn from stuff that requires a bit more tuning or customization.

In airsoft we had people who didn’t even know there were other options show up with $40 clear plastic guns from Walmart (they’re awful) and guys with $2000 air-powered guns from the best brands show up all the time, and both of these people sucked. Typically, they both also had a bad time, because neither could realistically learn anything from their guns considering they were already as good as they were ever going to be.

My advice was always to start with a low-mid range electric rifle that can take a high-capacity magazine. Having like 400+ shots in a match is more than enough. Pick a design that is easy to get parts and accessories for so you can build on it. Someday you grow out of it and then you drop the real money on an airsoft rifle, but you can run a good starter rifle for a long time. I only replaced mine because it catastrophically broke after years of rough play: I learned a lot from modifying it and it made my next gun choice much more educated that I ever could have managed as a newbie.
