How much distance are you looking to get out of your thrower? And do you prefer hand held (traditional light) or a spotlight? I'm really happy with my Dorcy 41-4299. It can be had for around $50 shipped, and if you order from dorcydirect.com you can order spare batteries for about $6 a piece. It's 220 lumens, but you'll have a hard time discerning between 200 and 250 lumens during actual use. I've had mine since August of last year, I use it almost every night. I usually let it run for a little over an hour before I recharge it. It can run for significantly longer than that, but dims quite quickly after the hour mark. I've got an extra battery that I keep charged too, add that with the house and car charger, I can keep cycling out batteries for as long as I need the light. The only downside is the NiCad batteries, but as long as you try and discharge them as much as possible before recharging, you'll be just fine. And at $6 a battery that, if abused and recharged constantly, will still last at least a year, big deal. When it's completely dark, I can clearly make things out at 200+ yards.
I'm sure somebody else will chime in here and give some other suggestions, but <$75 for the light, house and car charger, 2 extra batteries, and a UCL lens from here (52mm)
