It has been discontinued and the MSRP is over $50, but if it can be had for under $50 (which happened often) then it is a good deal.
Speaking of deals, when looking for a deal you shouldn't limit yourself to a particular brand/model. Identify several that will suit your needs, and find the one that is cheapest. Here are likely options:
Corsair CX430 (think of it as a decent 380W)
Antec NEO ECO 400C
Antec EarthWatts Green EA-380D
Rosewill Green Series RG-430
SeaSonic SS-350ET Bronze
If buying online in the USA right now, I'd do the Antec NEO ECO 400C
from Newegg.
