X3600H is 899£ at PT with 3year warranty. X4500H still 999£ with 5year warranty! At this time last year X4400H was 799£ lowest i think. Because no new model (X4600H) this year the price is kept higher. Black Friday is coming soon...So the the 3600 and the 4500 are now at the same price,which one should I get?
