beer tap spanner?

[moderate order]

Built myself a kegerator, only to discover that I apparently need (yet another) specialised tool. The 'nut' that tightens the tap onto the shank is cirular with holes equally spaced. It looks like I need something like this: Larcele Hook Wrench for Nut, Side Adjustable Spanner YYBS-01 (Round Head,3/4-2inch(19-51mm)) : Amazon.co.uk: DIY & Tools but is there a cheaper (bodgier) way I've overlooked?

I used this to assemble mine:

You only need to tighten the ring finger-tight. I have 7 taps and none have ever leaked - even at 50psi (nitro).
