1/4" valvePersonally I used a 1/4" MIP MIP valve along with some fittings from I think Lowes. I did however, swap the valve out for one from pexsupply.com as they have much better valves. I also have a 1/4" plug in the end just in case someone bumps the valve.

Using Rectorseal Steamaster water treatment to greatly reduce corrosion in the boiler.

Sight Glass Ball ValveHi- this is the best setup I've seen
Found this valve on AmazonVery similar to Steamhead's setup.
I have this one installed on my Megasteam 396
I'm cheap.I use these: http://www.harborfreight.com/14-full-port-ball-valve-68254.html1983(?) Peerless G-561-W-S
3" drop header, CG400-1090, VXT-24
Careful!That Harbor Freight valve can handle the pressure, but is rated for air line duty. It probably doesn't have a temperature rating and the bottom sight glass drain will be exposed to water from 212 deg. to as hot as 250 deg. at 15 PSI. Give me the valve rated for WOG and at least 250 deg. on the seals!
