Wanted: a bidding mod

My bank alt plays the AH like a battleground.

He'll buy & sell Runecloth constantly, snatching up bargains whenever they appear and flipping to a more regular price. One tactic he also deploys is to bid on all no-buyout auctions. He'll do this even if the item has 48 hours yet to run, knowing full well that someone else will come along and place a higher bid.

So why does he do this? Well, there's a small chance he'll actually win the auction with his bid of course, but more importantly he's forcing the floor price upwards. If his competitors win the auction at a higher price, it means they can't flip it at a lower price. There's also a small psyop element in play in that with constant re-bidding he'll simply exhaust the patience of some other players, letting him win more of the winning bids.

Now, there are auction house mods that facilitate ninja-bids -- placing a bid on items at the last possible moment -- but what I'm looking for is a mod that will place bids from the get go, and do so repeatedly up to some maximum bid, and do so on multiple instances of the same items (eg. those 23 stacks of Runecloth on the AH with a minimum bid of 6 silvers).

Suggestions?
