air ratchets

[Jonathan Miles <MILESJE@novell2.bham.ac.uk>]

I am considering buying a 1/2" air ratchet and I'm pretty sure which 
make I'm going to get.  Problem is, you can buy it on its own, or, 
for about twice the price, as a kit with sockets etc.  My question 
is, Do I need the sockets (are they impact sockets?) or can I just 
use ordinary sockets from my hand ratchet set?

Thanks in advance,
