Hid hut bulb question

Hi! I'm making my first bulb purchases and need to know if you like the HPS and MH bulbs from Hid-Hut?? The 600W HPS puts out 95,000 lumens and sells for 35 bucks. The 400W MH I want is also 35. Anyone use these bulbs?? Hid Hut indicates that everything about these bulbs is equal to or better than the usual suspects..that cost 89+
But they are selling them.... http://www.hidhut.com/catalog/hid-hut-bulbs-c-23_48.html

Thanks!
