Whatever you get,make sure it has metal caster wheels.Depending on how hard he is on it,run over a nut laying on the floor could break plastic wheels(done it).Make sure you get one with a wood platform,plastic ones are just too flimsy.Brand names don't really matter since their all made about the same.Never heard of anyone customizing a creeper before.

I think you should save that money and get him a brand name 3/8 drive ratchet and socket set instead. Previous two answers already pointed out that creepers are pretty useless if the car is not high enough and the ground is not smooth to allow free movement. Creepers are like car ramps. They look useful but they're hard to use and are not worth the money. Addition: In that case, I remember using a plastic one called Jeep Lisle or something. Really comfy with padded headrest. It looks like this one:
