Buy computer monitor cables from these guys a bit for work, always very fast service (4pm cutoff for same day despatch) and had no problems with any of the products.

Had these guys install some Invisiguard screen doors on my new house, they were the best price I could find after contacting a few places and more helpful than most. The installer was a bit slow and hadn't brought all the doors with him, or the right tools, so had to get someone else to come and bring the missing doors and more tools, but overall very happy with the service and product so far.

Approximate cost: $4000
