Hi,

I think the main difference would be the size? If your building it yourself then you can easily decide how many clutches you need it to hold and change the design around to make it work. It generally doesn't increase the cost all that much.

I have also heard people complain of failures with hovabators that cost them the clutch - Though it was always the thermostat they mentioned so possibly using an external thermostat gets round that. Mind you that adds at least another $80 to the price I think.

But then you don't have a thermostat listed for the D.I.Y either so you need to factor that in.
