Comparing 2 smaller tabletop fans, the Vornado 530 and the Chung Yuan Electric (The Home Depot/HDX brand) TF-810S.
Overall the Vornado packs more power for the size at full speed, but is quite noisy and considerably more expensive. I'd say the HDX unit is the better value of the two unless you need as much power as possible out of the smallest size as possible.
