there is someone been used Quick Auctions ?Follow

I would suggest trying either www.wowinterface.com or wow.curse.com

Either both or one of them should have it.

If you've been using Quick Auctions 3, it has been discontinued as of patch 401 by the author. It has been forked into new addons, one of which being Zero Auctions, which I use in place of QA3.

I A heavy user of Auctioneer. Never heard of Quick Auction. Does it use less memory then Auctioneer? or any better?

Auctionator is awesome. It's like a trimmed down Auctioneer. You can't make it play the game for you, but it'll scan and all that jazz.

It's a completely different style of addon. Rather than manage market prices and offer the ability to post based on calculated market prices, QA and it's forked addons post based on a price range you specify ahead of time. While Auctioneer has this feature, QA also has a few other types of features, like the ability to automatically send certain items to specified characters, tell you how much mail you have left, allow you to smartly cancel auctions you've been undercut on, a crafting queue, summary window and a few listing options that will allow you to undercut to a certain price; once that price has been undercut, the addon won't undercut below that price.
As for memory usage, I can't comment on it since 1) it doesn't bother me that Warcraft uses 1 gig or more of memory at times (I run 8 gigs of system memory) and 2) I've never checked.

It's really hard to say honestly. Each add on does something different, or does the same thing in a different way, which is why I prefer to use more than one. A combination of Auctioneer and Auctionator is really your best bet in my opinion. Make sure to get the Auctioneer suite though, not just the regular one. I use Auctioneer to scan the AH and to post auctions. I use Auctionator mostly to buy and save different shopping lists.
