I know I seemed to be in the minority on a previous thread, but I wouldn't buy one without a drier. I have a combined unit, and believe me it works extremely well, although I did get a fairly expensive model very cheap as an ex-demo and it was worth a lot more money than I would have spent if I'd been buying a new one.
A friend of mine has a blaster on its own - effective on warm days, but if we're bathing the dogs on miserable days she always gets me to bring mine as it is much more efficient with the heater.
Just my two penn'orth, anyway. Might be worth asking the big manufacturers if they have an ex-demo models for sale, I'm sure lots of them must update models before Crufts.
