Just went through the same buying process as you, with exactly the same criteria...
Some of the reviews I found for the 453 said it was a touch underpowered. If you can swing it you can get the much higher rated 456 for £135 delivered, in the anniversary edition from here, I literally bought this exact drill from them last week, and have since put down 500 decking screws, and done a shedload more on one battery charge, the 3 amp battery is brilliant.
