Wow, that's impressive. I don't think anyone is going to be able to beat that, under test scenarios and especially in real life use. Give the man a medal.
I guess this means everyone can be optimistic about using eneloops (and clones like the IMEDION's) on the K-x.

It's certainly worth trying for and probably not impossible to get 1000 shots out of a set of eneloops on the K-x.
I am also a eneloop user and have taken a lot of measures to minimise incidental power usage. Although I do keep lens and CA correction enabled if I am using a modern Pentax lens, I do have Shake Reduction turned off by default, for example. I also have the camera stay 'dark' all the time (not just for power-saving, but because all these features annoy me), by disabling the blue LED, turning off the status screen, turning off instant review, turning off the mode dial guide display as you switch between modes etc etc. Oh, and I hardly use video or LV.
One day I will start a process to test exactly how far I can stretch a freshly charged set of eneloops.
We need a contest here to see who can go the furthest on a set of eneloops!

Note that the K-x manual only claims about 600 shots with eneloops. A similar camera (related sensor, same video capabilities) like the Nikon D5000 only gets just 510 shots per charge out of a dedicated lithium battery pack. You can expect decent performance out of the K-x on eneloops, but don't expect miracles :)

I didn't mean to offend you by dissing your favorite SD card brands. LOL
But problem solving is all about eliminating variables, and a big variable here was the SD card type. The Sandisk's are a known baseline. Many people have reported that they work reliably for regular shooting and video on the K-x, and (I think - somewhere on the Pentax USA site) Pentax have tested them etc. So in eliminating SD card as a variable I wanted to recommend going back to a known baseline. If the Sandisk's worked OK, saving images quickly, then the issue would more likely be not with the camera, but with the cards you were using. And so on.
But I'm glad the issue has gone away now. And once again sorry if you were offended by the tone of my response.
I do however sometimes wish folks would not assume a manufacturing flaw is behind every issue or problem they encounter with complex devices (with 300 page manuals) like modern DSLR's. :)
If I were to drive my car everywhere with the hand-brake on, and felt the car was driving slowly, I wouldn't rush to call it a defect in the car.

I would hesitate to assume that there is any issue with your new Pentax at all due to the delay in image review you describe. I wouldn't rush to any conclusions.
Two issues spring to mind here:
(1) Why are you using those cheapo no-name SDHC cards? Get a Sandisk Ultra or just a regular Sandisk SDHC card and try again. Really, all SDHC cards are NOT the same, as many threads in this forum will attest. You need quality SDHC cards in your camera if you want it to perform to specification.
(2) The camera may be taking time to display the review image because you might have enabled some options that delay the processing of images taken by the camera. Options that spring to mind include: using RAW+ (ie two images get created for every photo), and turning on the options to implement lens distortion correction and CA correction (Menu > 1 - Lens Correction > Distortion Corrrection - Lat-Chromatic Ab Adj). You may have also enabled other image processing options like D-Range Correction (Highlight and Shadow Correction). The more you ask the camera to do, the more work it has to do in order to capture, process, save and display the image. The lens distortion and CA correction feature in particular can add a second or two delay per shot, as noted in the manual. It's the same story with RAW+.
