Hi everyone, I need to buy some sort of nodal head for my tripod to do real estate tours. Business has picked up amazingly and I'm flat out. But one of my clients wants virtual tours. He has the software (it's a big real estate chain) to stich it all - and it does a great job. But I need to reduce the parallax because I usually shoot at 10mm. So any recommendations on a Nodal head? I saw a reference to this: http://gregwired.com/pano/Pano.htm by ksmattfish a while ago. Does anyone know if they're still good? They're certainly cheap. I've looked at some manfrotto stuff - but I'm unconvinced at the price. Anyway, I need to buy this quickly - my first tour is on Monday and I'm just going to wing it with my gear I have at the moment. eeek.
