That would be my choice - great output and not overly blue. If you're into the bluish look they might be a bit white for you.
If you like the bluer look, the Ushio 20Ks would be a good choice as they still have good output (although less than the 14Ks).
Hamilton 14Ks and Coralvue Reeflux 12Ks are also popular choices - again both have the bluer appearance. They won't have the output of the Ushio lamps.
Also, remember to be careful when you switch lamps. Any of these bulbs will probably have quite a bit more output than the eBay lamps you were running. I would plan on reducing the photoperiod and/or using the window screening method so as not to bleach anything...
