If you've a local Wilkinsons, they're very good on this kind of stuff. I just bought a set of cheap utensils from G O, but whether they buckle under the weight of my home-made burgers remains to be seen!
Wilkinsons, Poundland & Poundstetcher do a lot of this sort of stuff cheaply. Don't think Poundland sell it all year round though so you might have to keep popping in,
If the utensils are plastic, you can "customize" them quite easily! I got a set of 4 for 10p once but they had long handles - soon remedied with the breadknife!!
