I asked a similar question back when I was looking for a host.
This is my thread: https://budgetlightforum.com/t/-/22639
The UF-T20 seems like the best and is like $22 shipped.
I know, it is over your budget by $6.80, but probably worth it to get an XM-L led over the XP-Gs in terms of lumens.
http://flashlightwiki.com/Cree Emitter to max lumen charts.
It has a XL-L emitter, not sure on current draw.
I didn't end up buying a zoomie though.
I Read about the percentage if brightness between the Domed LED and the Aspherical lens and supposedly the light looses about 40% of brightness after passing though both curved lens.
I went with a C8 and think it blows my old XM-L T6 zoomie away. But if I ever do buy another zoomie it'd be the UF-T20.
