Warning DO NOT order from that Techronic's company, iv never ordered from them, but they seem a lil Sketchy.
Order from places like www.sonicelectronix.com and www.audiosavings.com
But im agreeing with everybody else for around that price id go with AudioQue or Sundown, or just buy Used from someone thats trusty on here.
AudioQue http://www.audioque.com/aq/?page_id=26 <<< Sick amp(iv seen its big brother the 2k in person, good build quality amp)
Sundown http://www.soundsolutionsaudio.com/store/products/Sundown-Audio-SAE%252d1200D.html << Sick amp(from all the reviews i have seen, and i have seen the Sundown SAZ-2000 in person, and there build quality look good)
Rockford Fosgate http://www.sonicelectronix.com/item_2809_Rockford+Fosgate+Power+T10001bd+-Silver-Red+Box-.html <<< sick lil amp, but has a Rattle on the front of almost all of them.
Rockford Fosgate 2 http://www.sonicelectronix.com/item_9850_Rockford+Fosgate+Punch+P1000-1bd.html <<< Never tested that amp or seen it in person, but its a Fosgate, so it should be good.
