I also went on a Mr P search today in Savannah GA, no luck though.
ALTHOUGH, I did stop by Target and they had the "Karate Chop" 12" Buzz, and 12" "semi less accurate" woody on Clearance for $12 each, there were alot of each. Also the new boxed, but still shitty, slinky dog was half off as well, at $7.48. So Check your Targets. (The 12" "non-collection" woody and buzz, are still pretty damn cool in they're own way, and for $12, its a perfect kids gift (or adult!))
I'm currently working on sculpting an ACCURATE Slinky Dog, so I should have pictures by this weekend. The TS Slink came BEFORE the newly designed slinky dog, and they never got it right. The slinky dog in the movie was based off the original slinky dog pull dogs, which looked like this:

(bottom left)
Then, Jamestown put out this after Toy Story came out:
And we've had only that ever since.
In Toy Story, Slinky was designed as a wooden "1 of a kind" Thats why he looks wooden, and has no seam lines as the other plastic toys do.
So thats what I've been sculpting, using an actual Slinky for scale, as well as thecurrent slinky dog for scale. It will have:
leather ears, not faux
Jointed feet (at ankles), with wheels
and my favorite: a custom sound chip with a few Jim Varney phrases.
The parts themselves will have seams out of the mold (doing the sculpt in clay, silicone molds, and urethane resin-plastic castings) but I will sand them away. His legs will be the correct size, etc. So that way FINALLY, his damn slinky can sag like it does in the film, and with the added weight of making the castings solid, it will STAY in position.
If thats a success, I'll do a Bo Peep. (And possibly that robot, with fellow member Kyle).
And with the Mr. Potato head, I plan on doing a silicone pour of his current eyes, do a clay pour into that, and correct those mother F's to where they should be, SEPERATE. And with the 2 eye holes already on Mr. P's body, it will be easy as hell. That alone will make him look near %100 to the movie. (eyebrows seperate too, adjustable via self tack backing)
I'm sure the feet issue can be solved too, even making them seperate, removable. No need for the electronic BS, really, as most of us ARE collectors and not children. IE: Rex. Should've JUST been hard plastic, no sound, etc. I would've paid the same $40 for the TSC REX if it were hard plastic as in the movie, and ZERO sounds. Cheap looking, but not actually in materials and sophistication with movement (Jaw, etc) which is and should've been possible on the REX we all got.
If I sound like I'm nit picky, it's because I am. Pixar has the ability to give thinkway the computer files, and print DIRECTLY the characters, and every detail etc. They call them "replicas" but they're far from what they could be with some TLC, luckily, as thinkway DID put out great product. I'm happy as hell to see these. If you think I'm nitpicky, then imagine how I felt in 95 when they SUPER crap TS product was out, hahaha. But, all joking aside, not everyone can get a toy, let alone, several, so I'm always thankful when I do.
I look forward to LOTSO Bear! Also, the old "phone" in TS3, can be found at most Targets in the "classic toys" section. Its a must have hahah. I remember my little brother playing with one as a kid.
