Me and my friends looked into this a couple of days ago and we're all very enthusiastic on buying one (especially with the pistol grip.) Only fault is how much it's going to cost us considering the crash of the pound and the fact they don't sell in or to the UK

It certainly looks like a great innovation. I was very keen on buying one at first, however I think it might be a bit of a novelty item. Players on TF2 will probably find themselves getting beaten a lot, not because the falcon is less efficient but because everyone's had years of practice with a mouse. However, I'm sure it'd be great fun on Half - life, so I might still get one just to replay it and all the episodes.
