Which external flash for NIKON D40 ?

[MURPHYSIMBA]

I know the NIKON D40 camera comes with a built in flash but I need something that little bit bigger with a stronger flash

As part of my job I occasionally take photographs of the inside of newly refurbished buildings ie before and after shots (I know - not very exciting)

I have used my own NIKON D40 camera for this but have found the flash not strong enough for very large rooms (accommodating 70 - 80 staff)

Any advice on which external flash to get (£100 max)

Thanks

A candle or torch.

I know diddly squat about your system BTW.

Am not familiar with 3rd party but sb400 seems the best bet, although the sb600 is far better but double your budget.

Hope it's not too late, go for a Nissin Di 622. Does most things the SB-600 can do and is under a hundred notes. Better value than the sb-400 totally.
