Collision Avoidance Systems

At the risk of reopening some conversations that were archived from
2004 & mid-2005, does anyone have any up to date experience with either
the ProxAlert R5 or Monroy ATD 300 collision avoidance systems? I've
got a SureCheck TPAS 110 that I have found to not be very useful due to
sporadic readings and the lack of altitude feedback. I also used to fly
a G-1000 equipped C-182 with TIS that was great for traffic alerts (in
regions where TIS was available).

I now have an experimental aircraft where I'm looking for something I
can mount in the panel that will provide useful collision avoidance
information. I'm assuming panel mounting one of these systems will mean
I can set the antenna up permanently in the aircraft so the antenna
positioning issues won't be as much of a problem for me.

The Monroy ATD-300 and the ProxAlert R5 both look like options. The
Monroy looks like it is better suited to be panel mounted, but I've
seen a lot of reports of inconsistent dist & altitude readouts (all
more than 1 year old).

Since most of the Aviation Consumer and newgroup feedback on these
systems is 1 year+ old, and there was talk that all of the competing
companies are consistently addressing these issues, does anyone have
any recent experience with these units purchased in recent months?

Thanks,
Eric
