I have come to the realisation that I am a complete Logitech shill...

I recently updated my kb and mouse setup and now basically all of my peripherals for gaming are Logitech. (I know I posted before about looking at the Mad Catz RAT 7 MMO mouse, but I scaled back a bit in order to afford the keyboard).

That is:
G430 headset
F310 gamepad
G710+ keyboard
G502 mouse

And just because that wasn't enough my wife also has an M325 mouse on her laptop and a K400 keyboard for when we hook it up to the TV.

It wasn't planned this way, it just kind of happened. (Well, it is fitting, we do live in Switzerland!)

Is anyone else out there a single supplier user or do you prefer to mix and match? Do you use whatever is at hand, or deliberately set out to make a gaming rig?
Just interested in the peripheral setups that are around.

Two sets of Logitech speakers. One for my desktop, and a USB powered set for my laptop.
Logitech keyboard & mouse combo. Gave the old (Logitech) K&M combo to my brother.
Kind of old Logitech Dual Action Gamepad controller, it's called. Resembles a PS2 controller. No rumble.
I've got a Logitech C200 or something like that webcam.

When we had our Windows 98 computer when I was a kid, my dad used a really cool four button Logitech joystick with a throttle and POV hat.

I guess I just really, really trust Logitech stuff. It all works well, and I like the feel of it. I can usually get it for a good price, too!

Logitech have been making solid stuff for years now so I'm the last one to fault somebody for sticking with that brand. Good products, good prices, good reliability, good selection. What more could you want?

Yupp... I have at home a VX nano for my other laptop, and for work/gaming I use a K350 keyboard and an Anywhere MX mouse. I'm not really satisfied with the battery life of the Anywhere MX, and the keyboard's "H" key can occasionally get stuck. Ah and the VX nano has a small issue when selecting stuff as it sometimes releases the selection without any apparent reason. I wonder why do I keep buying their shit :)

I tend to buy things as and when needed, leading to an old friend of mine to label my computer set up as a chimera. My mouse is packard bell (and my husband's threatening to buy a new one as the scroll wheel is iffy), keyboard is Microsoft, monitor is LG, speakers are Gateway 2000 (which the company stopped trading in the UK around 2004 or earlier), headset and microphone is Creative, gamepad is an XBox 360 controller (so another Microsoft product).

Generally, I will use stuff until they wear down, then stubbornly stick with them for a few more months.

Same as well. I kinda like the xbox360 controller, native compatibility and weight wise, but the Logitech one gives me much less pain after long periods of use (my2cents => you recognize an ergonomic design after a long run)

Keyboard, mouse, speakers and a 360 controller.
I still need a headset or a microphone, some kind of communication device.

Edit: Oh and a monitor, mustn't forget that.

Can only agree to this. Using a G500 mouse, K310 keyboard, and Z523 speakers from logitech atm.
The only thing I don't like so much is the F310 controller. It works great and all I just don't like the plastic feel that much.
I never had another controller so I can't really compare.

And for headset I use a Siberia v2.
