Buy Ps4 with accessories for 350 CHF (317 euro). Too much?

I want to buy the ps4 from a friend he charges 350CHF (317euro). Where:

ps4 with 1tb SSD storage. He made the SSD in himself (because it is faster than a normal storage medium) it costs 100CHF (90euro) and is one from Samsung.

2 controllers both original

a controller charging station

a good wireless headset name: "turtle beach 700" costs 160CHF (145euro)

a small screen that is not worth much is also rather older (also one from samsung)

is that a fair price? All items are used I don't know how much that affects the price, but everything is in good condition

Well, what a "small screen" that can make a lot of difference. What kind of headset? Any games? The question is because, if you can name the model names of the items listed, I could suggest an even higher price. Depends on things. Should be a relatively fair price for the equipment.

PS4 1TB with controller can be found on classifieds for 200 euro.

You just have to think about whether the other stuff is worth 120 euro to you.

There were no games, the TV wasn't worth much, he said, and the headset was around 100

Yeah, the price is okay. Do you know how much heart the TV / monitor has?

Too much in my opinion
