Ordered one of these for someone the other day from the Reading branch of JLP. You can still get it direct with the 6 year guarantee if purchased before the 31 Jan 2011.
You have to get an under-sale done on the machine as it is currently with them at £490, however the local Panasonic store is selling them at £429.90.
You can do an under-sale online but will take longer than the 1 day you have to buy it. Or you can just buy it and run the under-sale after.
The reason being is that JLP are offering the 6 years parts and labour which is exclusive to them and will honour this with the under-sale.
