Where to buy valves

[IrishDave]

After a piece of metal found its way into the engine and took out cyl4 I am rebuilding. More than likely 1 or more of the valves were damaged. Where is the best place to buy individual standard valves. I'm sure the stealers are pretty expensive so is there anywhere else.
Thanks

I have a few sets

I'm not really looking for a full set. Worst case scenario 5 valves, but pm me a price on a set.
