Dew Controller Recommendations - Imaging?

[Trull]

I'm going to buy a dew controller for my Vixen ED103, DSLR and guidescope. Has anyone any experience with imaging and the other brands apart from Kendrick?

ie:

Dew-Not

AstroZap

I'm interested to keep stray RFI to a minimum, as I also have a home brew ultra low frequency radio wave detector which I may want to use at the same time.

Any insights/snafu's/thoughts would be much appreciated

you might find it profitable to use a simple variable power supply. No RFI and very likely cheaper.

I have a "Dewbuster" controller with "Dew-Not" strips, excellent.
