You can also go to Bartle&Gibson 13475-Fort rd 472-2850.
They sell:
M57 ballast for 62.70(175wt)
M58 74.25(250wt)
M59 75.00(400wt)

Make sure you go to the one of Fort rd. I made the mistake of going to another branch without calling ahead of time, and they didn't have any. As for the socket and reflector, I just got a DIY kit from J&L.
Including the two 175watt ushio bulbs I got, I spent around 450 bucks on a 2x175watt setup.
A single 250 watt setup would cost around 260-280 bucks including bulb, a good 12" reflector, and ballast.
