Here are some choices but I don't know how well these will work for you:

Batman (2003)/DC Superheroes Robin (Tim Drake): This figure is old so it's under articulated compared to DC Icons. But it should be cheaper than most DCUC Robins. It was released a few times with different decos so look closely at eBay auctions to see which is being sold.

DCUC Series 3 Robin (Tim Drake): The Dynamic Duo Robin was redecoed from this figure. It's still expensive but you might be able to get it for less than $50.

DC Young Justice Robin (Dick Grayson): This isn't the classic costume for Dick but he comes with a lot of accessories and you should be able to get him for around $30.

Batman Missions AF line: This is Mattels current line of Batman figures for little kids. It's Batman heavy but it does contain some bad guys and a Robin. These are basic figures so paint apps and articulation will be lacking.

Like Bo said, characters that can change their size like Clayface or are known for being really big like Bane can be purchased from other lines that are in a larger scale and used with your DC Icons figures.

Just out of curiosity, why don't you like the DC Icons Robin?
