Digging fork recommendation

Hi All
I have just broken my fork (after 15 years faithfull service)
I wonder if anyone has any recommendations for a decent replacement?

it had wider tines than normal (I always called it a digging fork, but it 
may be known as a potato fork??)
also a longer handle (I am over 6 feet)

I am sure it was not too expensive when I got it
but I can't replace it directly because I am not sure of its make since
its 
label has come off

any thoughts?
