Ring flash.....can't justify the Nikon

[PhotoriousMe]

I'm in the market for a ring flash for macro photography but the Nikon and top brands are not cheap. Now I know you get what you pay for but looking at the mid range ring flashes there seems to be a few that have decent specs. Can anyone comment on the Meike TTL MK-14EXT LCD LED Macro Ring Flash? Or maybe recommend an acceptable unit under $150 or so. Thanks
