Purchased one from Amazon/Tigerdirect. It comes with 2 sets of cables. Installation was easy and intuitive and it worked like charm for both keyword and mouse (I used both USB keyboard and mouse and had USB-to-PS/2 adaptor for both). However, it gave me highly blurry image output (LCD 1600x1200) compared to direct linking from the computer. I tried to downsize the display resolution but the blurriness was still visible. Decided to return it!
The good thing about it? (If you really do not care about the image quality which I dont think so). Easy installation, no power supply needed, free 2 sets of cables, easy hotkey from the keyboard, stylish design etc.

The D-Link DKVM-4K is a solid PS/2 KVM switch that supports monitor/keyboard/mouse sharing between up to 4 PCs. It is ideal for home users with multiple computers, or for use on a troubleshooting bench. Switching between PCs is accomplished either by pressing the button on the device, or by pressing a series of keys (scroll lock + scroll lock + computer number). Switching works well, and I have noticed no degradation of video. The only minor complaint that I have with the unit is that it comes with only two sets of cables, which is not mentioned in the Amazon description, so if you need to use it with 4 pcs (as it was designed to be used) be sure to buy two extra KVM cables.

I'm using an Eizo S2100 lcd monitor and an ATI FireGL V3100 adapter. At 1600x1200, the image is noticeably blurry compared to connecting the monitor directly. Using the phase adjustment on the monitor, I could clean up the image enough to be usable, but it is still not as sharp as before. If image quality is important to you, you will probably want to choose another KVM.

I spent three hours on the phone with D-Link tech support (India) trying to get a simple compatibility question answered. I finally spoke to someone in the corporate office who said they would connect me to a technician in the USA. When she transferred the call all I got was a recording saying the office was closed and call back on Monday. I packed up the switch and it will go back tomorrow. Their customer service/tech support is non-existent. I urge everyone to stay away from the D-Link brand.

This KVM switch connects up to four computers as expected. Two cables are provided, the other two you have to buy yourself, and be sure to get Male-to-Male KVM cables (not all KVM cables are the same).

Biggest limitation of this KVM: The video quality is not good enough to support a 1600x1200 resolution on my normally-crisp 19" Insignia CRT screen. I had to drop my resolution down to 1280x1024, and now it is good enough to get by.

The beeping problem is well documented here. I don't mind it, but it could annoy some. Basically, there are two beeps when you switch computers. By pressing "Scroll-Lock", "Scroll-Lock", "B" you can reduce it to only one beep, but you can't completely silence it as hoped.

I am keeping the product because it is priced well for what it can do. But if you are a stickler for a sharp picture at higher resolutions, you may need to look elsewhere.
