HPS BULBS, best options

I'm starting a grow very soon where I'll need multiple HPS bulbs. I was wondering if anyone has a history with a fair priced, efficient bulbs. More so, best bang for your buck kinda deal. Nothing like Hortilux costing 70+ or whatnot. Any advice would be appreciated, thanks in advance.

250W Bulb*

You haven't communicated the wattage you are trying to use but If you just want a simple HPS in either 70, 250, or 400 watts, then go down to Lowes and by a simple utility bulb. The high end bulbs are designed for agriculture and create an improved spectrum as a result. Some believe in the improved spectrum bulbs and some don't care... Its your call. Phillips makes a decently priced agro bulb that is cheaper than a Hortilux. Go Ebay for the best market and price.
