The Silvia is a fantastic machine but if you want heaps of hot water the boiler is only 300ml and might come up a bit short. An HX machine is probably the best way to go for you but you might struggle to find one in that price range. You will also need a good quality grinder to go with the machine which will add $300-$800 to the purchase cost. Im sure you will plenty more expert advice from fellow CSers...good luck with making your choice!!
