Any set of well fitting screwdrivers will do. The important thing is to get a decent set in the common head sizes (Philips rather than pozi most usually). I got an admittedly cheap set of screwdrivers from Screwfix and they have held up well, if I had cash to splash I would of course get something better.

Take a look on ukworkshop forums, lots of cabinet makers and tool enthusiasts, a quick search will put you in the right direction.
