We have a set of Philips HR2385 scales. 5kg in 1g increments.
Weve found them to be very useful for our needs.
I think they were around $50 from memory. Not sure if they even make this model or equivalent now.
There seem to be a few different types around with the 5kg capacity. Perhaps one of the big homewares stores or department stores might have a few to look at and compare.
There seem to be a number of this style around too on various web/auction sites for ~$20
