I don't think the price is that bad if you're still really into the game. I've fallen off the MW2 train, it's all about BC2 for me now. However if you're still totally into MW2 then it's probably a price worth paying, even if two of them are repackaged COD4 maps
The one taking place in an apartment complex, which there was a loading screen picture released/leaked of, looked pretty cool.
Still slightly irritated with the way things went after I got the COD4 DLC tho, really wanted to try out the maps and every time it was about to change to a DLC map everybody vetoed it. As a result I maybe played the COD4 maps 3 times each, since apparently no one else wanted to try out the stuff they paid extra for. Sigh.
