suggestions on 1xcr123 build

I am thinking about putting together a single cr123a light for a gift. thinking about the short convoy s2+ but am clueless about which driver to use. doesn’t have to be a poker rocket but would like a good balance between runtime and brightness. how would this boost driver from mtn electronics work (runtime/output). http://www.mtnelectronics.com/index.php?route=product/product&path=67&product_id=335

also any other host/ driver suggestions are welcome
