Probably not a life changer, but certainly makes life a bit easier, and may reduce your energy cost slightly.
I've had a couple of Bosch ones, that have been good, but currently have a Miele one which is much better. (Cleans better, quieter, better build, holds more.) Miele also make some with auto dosing which saves the minor hassle of adding detergent each time. (I've not used one or done a cost comparison, but I have a auto dosing Miele washing and it's very convenient )
I acknowledge they are more expensive, but in my experience are cheaper in the log run.
I prefer the cutlery rack over a basket, as it takes less space, cleans better, safer with sharp knives and easier to unload. I don't have a problem with glasses as the hight is adjustable on the cup glasses tray. (I think many people never realise it's adjustable).
I use Sainsbury's dishwasher powered, as it's much cheaper than capsules and tablets and works fine on mine.
You may want to consider one that has a delayed start, as some electricity providers have a lower rate over night, or yours may in the future.
You may find that you'll need more cutlery, cups, plates etc, in order to fill the machine efficiently.
You don't need to rinse plates before loading (this is a wasteful misconception), you may need to clean the filter occasionally and be aware how to clean the pump impeller (RTFM) as people often think their machine is broken but it's just a cherry stone etc stuck in the pump.
