Looking for a driver

So I’m looking for a driver for my project. It’s an XHP70.2 6V and will run on 2S 26650. Now, i have looked high and wide at dozens of other driver designs, and I have decided to do a constant current buck driver so I can keep the low voltage protection and keep my plastic host from melting. I don’t want to drop a ton of money if I don’t have to, so I checked the Orient first and am thinking of this one: https://m.aliexpress.com/item/32848673663.html?

Or if it’s a better option, this from Mountain: http://www.mtnelectronics.com/index.php?route=product/product&path=67&pr...

I like these because of the low profile inductor that will be easier to heatsink. The 17mm one is awesome, but at almost $30 with shipping, a little steep compared to under $10 for the Chinese one.

Thanks for the help!
