Have a great site, good prices and theyre based in Richmond. I work in Twickenham so I can pop down for a viewing and collection if I decide to buy through them.

Im going to compare the AX100, Z5 and TX300. Im liking the brightness of the AX100 as Ill I wont be able to block all ambient lighting. Then again the shadow detail/blacks and warranty of the Sanyo are also very tempting... oh and obviously the price Its a 100 quid cheaper than the other two.
