Following a recommendation on this forum, I have just purchased a 17" TFT monitor from Aria PC Technology. The monitor is produced by Digimate. For £140 including VAT and delivery, I have model specification includes 12mps, 300cd/m2 brightness and 500:1 contrast ratio.
Delivery was very quick, considering I ordered it on Boxing Day. Aria also provided a link to the courier, who in turn provided regular updates as to where the monitor was in the delivery cycle.
The monitor itself is very slimline and took less than 10 minutes to unpack, set up, and adjust. The picture is incredibly clear and bright, with not a dead pixel in sight. I would thoroughly recomment Aria to anyone looking for a TFT monitor.
