I got a 175w SE 14K bulb for my frag area from here:

Really like the colour, more like the 250w DE 14k Hamiltons I used to run, definitely more blue than my current 14k Ushio. Can't make a fair comment on growth as using a crappy old grow light ballast and reflector.
Price was 19.99 plus 7.00 shipping (in USD).
