i used to trim and shave, then i realised i was getting a lot of ingrown hairs due to that...
so now i just trim it really short.
have been using Philips Multi Groom set with the shortest setting for a while now.
Cheap and good... if spoil, not so heart pain, just get another one...
for reference:

Some online shopping portals have it even cheaper, runs only on one AA battery.
