I'm using A4tech x-748k mouse with bundled a4tech x7-200mp mousepad, Titanium tk101 keyboard, Philips shp3000 earphones with added Zalman zm-mic1 microphone for Skype and online gaming and i have Genius sw-2.1 355 speakers but i don't use them very often. All of those didn't cost me more than 180 PLN or in US dollars 45$ even though i have got them all brand new:P I would really like an upgrade but i don't have money for that.
