HVAC double line duct drawing

Hi everyone, I am wondering if some of you might be able to suggest some
programs for me.

I am looking for several duct routing programs to use within Autocad as a
lisp or arx or vlx or whatever else may work.

I would like something that will draw in double line ductwork (rectangular,
round and/or flat oval), transitions, turn-up's and down's, radiused elbows
as well as square mitered elbows with turning vanes, boot-tap take-offs,
flex duct, etc.

I've just downloaded the Sduct 4.2 program which works nicely. I would like
to find 2 or 3 more that I can compare against each other as far as ease of
use, quality and price. Sduct costs around $100 U.S. normally but has a
special going on currently for around $65 U.S.

Any suggestions would be great! Thanks in advance.

Here's another to consider .... http://www.asvic.com

A bit more in price but they offer modules so you can get what you need/want
and their support is there for you.

 

There is also Cadduct, Which is great for coordinationa and spooling, but might be out of your price range.

 

You may look at Caelink.com they have an HVAC Designer a little pricey but
you can try before you buy (30 days uncrippled). I have used there products
in the past and found them to be pretty stable and they work well
