Just entertaining the idea of getting an RTA. I see the Audio Control ones going for approximately $1000.00 used. I've noticed some people who are selling their RTA's mentioning they found something better. What would that be? A computer program perhaps? My questions are.....
What's out there?
Are conventional RTA's not worth pursuing?
What should I look out for if buying a conventional RTA?
Price range of 500 to 700 CAD........... thanks.

A Coustic RTA-33 can be had for ~$300US on Ebay. I have one as I purposely sought it out. It's the same size as a pullout CD player, runs on 110v, 12v, or internal rechargable battery, and was the only RTA other than the AC to be IASCA approved. Scoring programming is built in too.

i have a coustic one as well as an ac, both are great but i prefer the coustic, far smaller and easier to use but wont do big spl. the coustic is no longer available new(bummer). i bought mine for 100$ bucks off some guy that didnt know what it was but i see them occasionally on ebay. they are good to have and can be a usefull self learning tool

I'm going to get my butt kicked for this...but with exception to Tim, Dukk, Dave, and few others, buying a good book on sound will help you achieve far better results than an RTA.
I suggest The Loudspeaker Design Cookbook for starters, and the Autosound 2000 Tech papers are very good too.

I use a db meter and do tone sweeps for phun...
Flat reponse on an RTA dosent always mean much for SQ unless you have a meter that can take 10ms readings and ignor reverb, though...

The Autosound Tech Briefs are worth their weight in gold................no matter how much a person knows about EQ.............they will open your eyes and teach you so much more..................
I have heard they are coming out in CD or DVD format soon, instead of that 800 page binder.......

Haunz, not everybody is a SPL knuckle dragger, there are tons of people interested in the other side of the coin............SQ...........
You can use a RTA to find natural and unnatural peaks and lulls in a vehicles interior, adjust crossover points to avoid peaks from overlapping frequencies, as well as many other things..............it isn't just used for SPL burbs.......
