The downside of a combi is changes in pressure, flow and temperature when more than one person is using the system. eg you are in the shower and somebody decides to wash the dishes, it can be irritating.
However I do like combi's. Also a good idea to fit a control valve to your shower if you want to run it off the boiler, gives you much more control over temperature when having a shower. And yeah you get great hot water pressure.
Also, as far as I am aware, when switching to a combi, most installers will just link the inlet and outlet of your hot water tank and get rid of it. Some houses that can leave you with a long and pointless run off tubing from the boiler to where the tank was and eventually back to the tap you are using. So it can be worth having a look at that, and if it's a long run paying a wee bit extra (or DIY it) so save money in the long run and get a quicker response at the taps.
And talking of DIY, modern plastic pipe and push fit connectors are so easy to work with. So if you want or need to save pennies you can do a good bit of the install (if doing a full system) yourself.
Oh Toolstation do good quality radiators at really good prices.
And if you ain't keen on the idea of a combi, but don't want the expense of running a traditional tank system, check out systems like superflow.
