I use the cheap stuff from our local catering shop. I try and not to get stuff that's too easy to bend phyiscally because it adds to th effect if the spectator tries to bend it - especially the tine bend. You can do Morgan's routine with most cutlery - but starting with the cheap stuff alows you to get confident and build the correct strength (without giving too much away).
If i do the routine at a resturaunt and the cutlery is different I just explain that I'll get into trouble with management. When I'm performing I usually have a pocket full of cutlery and if I'm not at a resturaunt I joke about having just been at a resturaunt. It also helps to point out that the cutlery is stainless steel and give the spectator something to examine.
Fortunately most of the resturaunts (excluding the really expensive ones) use the the same cutlery as i do as they get it from the same catering place. You might want to find out where the resturaunts in your area get their cutlery.
Have fun with the routine
