I was at Gordman's in Peoria, IL yesterday and found some extremely cheap KO combiners. The combiners they had for $3.99 are pretty blah. If you've seen the KB Toys TF Universe version of Superion, they are that scale. They are pretty cheap and flimsy. The combiners for $5.99 are really nice for the price though. They seem to be in scale to the original size of the G1 combiners. The decals aren't great and some are missing, but overall they are cool. The have about 5 or 6 combiners that are the cheaper smaller size. The larger combiners they have that are larger and in the $5.99 price range are Devastator (yellow version), Defensor, and Superion.
They also have some two packs that are KO RobotMasters. One pack was Victory Saber. The only other RobotMaster I remeber seeing was Double Face. I think these sets were $3.99. I didn't pick any up yet. But I think I might go back tomorrow and get the Victory Saber set.
*Edit* I got the Victory Saber set today. It is almost identical to the RobotMaster version. There is even a sticker on the inside of the box that says "RobotMasters" and has the stats for Victory Leo. The only differences between this $3.99 KO and the real thing is Star Saber has red shoulder guns instead of black. He also is missing all Autobot decals and has replacement decals on his shoulders. Otherwise this set is the same as the real RobotMasters version.
