(Edit: Didn't see your post when I wrote this FlamedLiquid - looks like we did the same thing more or less
Holy hell - I originally bought a PS3 uDraw when Amazon had a lightning deal for $39.99 and then picked up Marvel and Pictionary from Best Buy during a B2G1 (and they were on sale for $29.99). I thought that a great deal. Now you can get the uDraw + one of those games for just $40 - unreal...
I did end up picking up one from Gamestop for $29.99 and then sending my other one back to Amazon. I'll get hit with return shipping but should still come out $5 or $6 ahead (plus using my Gamestop credit instead of more valuable Amazon credit).
I guess I'll just stick with the games from Best Buy since I also got Pictionary fairly cheap that way. Still, though, they cost me $20 each after factoring in the B2G1.
Me and the kids had a blast with the Wii Pictionary which I bought last year at this time. We only played it a couple of times though. I bought the PS3 version to "upgrade" to HD and trophies. Having to not look at the screen when the word is shown is somewhat of a pain, but we managed to do it and had some fun with guessing what each others drawings were.
The resale value of the Wii stuff is pretty high though. I managed to get a fair amount for my "like new" tablet, the Pictionary game, and even the uDraw Studio game separately (someone who bought a used tablet without the game bought it). There seems to be a decent install base for the Wii version which is I guess why some more games finally started coming out for it. I also thought it was interesting that the Wii version is not on sale at GS while the others are. Hopefully they put out some more games for the PS3/360 - even if they are downloadable (probably the best way to go for them, really).
