I bought my K750i in septembar 2006 for 10.5k
Bought an original Sandisk Gaming grade memory stick pro duo 512 MB with 5 years warrenty last month for Rs 1,500. The package was compleately sealed, I bought it from the sandisk distributer here, & since the card is transparent, i checked the serial number written on the chip on the net, found it to be genuine. You might pay a bit more when going for original, but its not like you buy a memory card everyday, so it's better to buy genuine
I bought HPM-70 earphones for Rs 1,345 from Sony World, which had the tag on the wire too, i noted the number, searched on the net & it was also a unique identifier, its genuine. The in-ear earphones give really nice bass...but I opted for Sony MDR E-818LP earphones insted for Rs 500 & taped the extra wire, cos i don't find in-ear comfortable for my taste, they tickle my ears actully
. E818 gives ok-ok Bass though even with Megabass equilizer, I was short on money or I would have bought MDR-J11G
Sony is about to relese HPM-64 soon, which is the same thing as HPM-70 but with normal rounded earbuds. HPM-70/64 is good as it acts as a convertar for your phone to 3.5mm audio jack & you can plug any speaker in it. Here is a pic of my HPM-70 with MDR E-818LP ear buds

One thing that I would recomend is the Sony ericsson Micro Travel Charger CMT-60, the reason is that, if you are traveling with your phone, then this is a really essential tool, you can charge your phone from 0% to 100% using 2 AA batteries, in just 1 hour. A handy life saver infact, cos there are no plugs in train usually.
K750i is a good deal, you can easily make it a jukebox like I did or you can get a pre-made Jukebox, the W810i, as it comes with 512 MB card & HPM-70 along with walkman branding & player. In both cases, the end cost will be about same. Right now going for a W810i is a better deal with a Travel charger, cos K750i's developement cycle is over now. For those who already own a K750i they can follow something like i did
