Hey there Paul
I recommend you get the HB Sport.
The blades that come with the Sport are triple blades, which last about three to four shaves. You can get the same number of shaves out of the generic blades that fit, which are cheaper. For example the Schick Ultra Plus or the Gillette Contour Plus, these work brilliantly!
You won’t regret getting the HB, once you learn how to use it properly.
