I just replaced 2 glow plugs yesterday.
I went to Sears and bought 2 ratcheting wrenches (12mm and 8 mm) for about $16. At the check-out counter, the cashier told me if I applied for a Sears credit card I could get $15.00 off. I said why not. So in essence I paid only $1 for the pair of ratcheting wrenches.
Then I went down to Autozone to buy 2 Bosch glow plugs for $7.99 each.
Got home and replaced the 2 glow plugs (#2, #3) in about 30 minutes.
