This great morph costs around £15 and well worth the money. Diffculty = 3, as you do have some palming to do but not really that difficult.
This effect is the best morph I've seen as the bill appears never to leave your fingers and the whole effect is done in one continuous motion with the hands always appearing to be empty. The only downside is that you need a gimmick not supplied with the video but you probably own one anyway, they're easy to get so a minor niggle. Suggest if you buy this you develop a routine about having the Euro here and money exchange etc and morph a £10 note into a E50 note, you'll see why if you get this. Even with the gimmick you can perform this completely surrounded if you've practised enough

I got mine from www.magictricks.co.uk and they've always given me good service so would recommend.
