You can ask some users in this forum for a code for a better price
M4DM4X has a discount code that takes about $5 off the BangGood regular price.
I really like my BD06 as a general purpose light since I have defeated the blinky modes with a solder bridge. Now it’s just Low Mid High without the strobe or SOS modes. Not the brightest light in the realm of 26650, but good output (they say 1000 lumen, I think a bit less) and a nice beam.
I don’t feel it’s big at all, unless compared to 18650 lights. Definitely not pants pocketable - but works in a jacket pocket nicely for me.
EDIT: as for the charging - a “dongle” (for lack of a better description) clicks over the side clicky button, then uses a USB cable to charge. The side button CAN be clicked with the dongle in place - I have been leaving it attached to the light on the shelf, and remove it when I take the light out. If the dongle is misplaced or left behind, of course the battery can be charged externally just like with most of my other lights. The supposed advantage of the dongle over the switch is a bit more closed seal than you’d get with the USB port under a rubber plug - Convoy says IPX-8. I have not intentionally exposed mine to weather/water/dust to find out, though….
I really think it’s a nice size to hold in hand and use, too, especially with the side clicky.
my 2 cents…
Ultrafire F13 original for $<13 might be a great starting point…

Easy, the DV-S9. Magnetic slider, moonlight to turbo, waterproof, 10mA parasitic drain but easy tailcap lockout.
Looove that critter.

Oh yeh, ~17bux at FT, but ~15bux and change with blf code.
Can’t go wrong.
Yeh, just got a few buck drivers for the beastie. Needs 22mm drivers, not 20mm.
I’d love it more if it weren’t blue… with a red bezel… :confounded:
Dang, I didn’t know FastTech did BLF discount! Is it just “BLF”? I just placed a $40 a few days ago… :cry:
Actually, it’s not that medium-blue like in the pix, but a really nice deep indigo. The red adds a splash of contrasting color, methinks.
And yeah, “BLF” still works.
Ah to clarify,
The BD series snap on is very clever for it does not hinder the use if the button and has a micro USB port
One can just leave it on when not charging it is holding in pretty good
Another vote for the UltraFire F-13.
Reasonable quality for just $13, easily modable & cheap enough not to worry if anything goes wrong.
A good light to begin modding with & the light recommended to myself & many others as a starting point down the slippery slope 
$45 with coupon code.
I was considering putting the guts of my DQG in that housing, but maybe I should build a new triple xml2 or xpl and leave the DQG as is. It’s too tiny! Lol
Let me know if you build it.
i dont think you said “reflector only, no zoomies” so…
i bought a “x700” light, just to say i had one? got mine form GB ’cos i had “some points” that would expire, and the light was on sale to boot… i think for under 10 bux, i got a 2 bay charger, 2 cheepie 18650s (for use in junk lights), and the light itself.
i actually like it, and its something of a goto light.
mine is the 1x26650 version… which i like. the driver ended up getting swapped out. i have several 1504’s from the n10siverrn group buy… had a replaced driver laying around, put it in the light i am describing here.
on low, its still more than useful at close range, and will run forever it seems like what with the 26650 battery.
cant wait to replace the lettuce-bright emitter with something better and complete the light’s transformation…
