If you are thinking of the 1054z and are happy with that price level then as most posts say, its probably the best buy at the moment.
( cannot blame you for asking the question here , I would like to see an up to date resume of the 1054 rather than trying to wade though the 1800+ posts on the 1054z thread in the Test Equipment forum)
Make sure you buy from a genuine EU Rigol dealer, so the warranty is upheld in the same country; many, but not all, Ebay sellers, though shipping from your EU country, the warranty is return to China, the actual location of the seller/supplier.
Also consider its longer term value, even Rigols old 1052 model is still demanding a high price on the second hand market, so the 1054z is probably a better investment than some cheaper devices.
