You should take a look at sponsors site there are lots to choose from there but you need to make your mind up what you want sat or cable or a mix of both as this will determine the price of the box..
I myself always opt for and recommend vu boxes if your using just for sat then you need a twin tuner box to enable recording one while watching another like the solo2 you can add a cable USB tuner for the best of both worlds and also get boxes already set up for both cable and sat...you can select a boxes that allows you to add tuners of your choice to a box with spare tuner slots to add mix and match etc...
There are so many choices so it's mainly dependent on your budget..
