This ones a little cheaper and has the ability to be aircooled with a $5 attachment.

And htg has good quality cheap products and amazing costumer support.

for the price of the one you posted you could get one of these 250 watt ones

Also i would recommend adding a foot to the height of your box for clearance of ducting and the light.

Because if you have a 3 foot box and a fan thats 6"-12" with ducting plus a 6"-10" pot you only have a foot and some change for actual growth.
