The 3000 is powered by kinetics, is much lighter, and the first person to touch the gun becomes the owner of it.
3000 slim
PSP 2000
I'd say the 2000 is better value for money. It is cheaper than the 3000, and the differences (different screen and in-built microphone) are not worth paying extra for.
It can depend because sometimes there's no difference but that's if your talking about the 3000 slim & lite but if it's just the slim & lite then that's refering to the 2000 slim & lite and the 2000 is the older model and the 3000 is an improvement of the 2000

The Least Common Multiple (LCM) for 2000 and 3000 is 6,000.
√2000 ≅ 44.7 √3000 ≅ 54.8 The squares of 45 to 54 lie within the range 2000 to 3000. There are thus 10 perfect square numbers between 2000 and 3000.

The PSP 3000 is a much later version compared to the PSP Slim and Lite (or 2000).The main improvements in the PSP 3000 includes a better screen colour and build in mic.I personally like the PSP 3000 more as I find the colours on the PSP 3000 better compared to the PSP2000.
