Totally what I would say….

May I ask why you prefer this system? For the same price these kits appear much smaller
Can be very cheap, and very temporary. Easy to store for next year. Add a light bulb and it's a hot frame for colder nights. VENT IT EVERY MORNING!

You might be missing how simple this can be!
Four cinderblocks, two 2x4's and some plastic drop cloth to cover it is the easiest! VENT IT EVERY MORNING! (Did I already say that?)
I once used the crib railing side of a discarded crib, propped horizontally on four cinder blocks and covered in plastic.
Here's some links to DIY coldframes and the strategy for using them from university extension sources:
