I have had two desktops and one laptop repaired by Kym's Komputers and I regularly purchase my consumables there and the service, price, advice and honesty is second to none. I often recommend this shop to friends and relatives.

I bought a computer, was installed in home, service was excellent as I know the owner, called him out of hours for technical support, looking back the hardware was slightly expensive but I can't fault the service.
The computer is still running well 8 years later, bought a keyboard from there recently, was very cheaply priced.

Approximate cost: $1100
