Thanks Trevor but I just checked Robert Whites and the Pups are now £180+vat. Seems RW and other photography retailers have put their prices up due to the recession.
If I thought I would get alot of use out of it then I would get a Pup but I probably would only use it a few times a year.
One thing I have learnt is that if you buy cheap you usually buy twice which is why I'm hesitant on the Calumet.
