Will this work for dimming 12V Halogen?

["Randy \"Brick\" MacKenna" <randymackenna@xxxxxxxxx>]

My existing transformer/cabinet halogen 12VAC lights simply flicker
and shut off when I try to dim them with my 20 year old x-10 lamp
module and 'mini controller'.  Even though the transformer says
"dimmable" on it, maybe it's time for an upgrade.

The new transformer engineer I talked to today said that his high-
quality dimmable transformer will work, as long as I use a high-
quality dimmer.

The tech at the home automation place said that his high-quality
Insteon dimmer will work, as long as I use a high-quality transformer.

Here are the two products I'm talking about:

Before I spend over $100 on this one circuit, do you think this
combination will work?  Anyone have any similar experience/success
that they can share?

I can't switch to 120VAC lighting due to in-situ wiring constraints.
Need to stick with low voltage.

Thanks,
Randy
