Heated dew shield

After losing a good few hours of imaging time recently to dew problems (despite using a dew shield) I'm thinking of getting a heated dew shield. I use a 130pds reflector and I'm wondering if a heated dew shield like this:

will work well with it or if a secondary mirror heater is a better option.

I'm using one that I bought from Barbara at dewheater.com, she will make it to specifically fit your OTA, a lovely friendly women who makes good kit.

They look good, would a heated shield work ok with a newtonian?

I'm really not sure, I bought it for my RC as I didn't want to apply heat to the secondary, it seems to work but I see no reason why it woudln't work with a Newt.

Thanks, I don't want to run wires and heaters to the secondary either, but I was a bit worried that the heated dew shield wouldn't prevent the the secondary from dewing. There seems to be a lot of condratictory info on the net about dewing.
