Depends on what you want. I want reliable connection at fair price. I was in your situation last year with Billion 7800N which burned out after two year warranty expired -- from forums, a common problem. £80 the poorer, I went back to the PN supplied ADSL router which worked just as well as the Billion both giving 10-12Mb depending on time of day.
At renewal Plusnet gave me fibre at same price as ADSL and their PN One/HH5 gives steady 35Mb from the day it was plugged in. Does all I want.
