Android phones in that price range are pretty rare...the Xperia x10 mini launched recently just about falls into that bracket. However it does not even have an on-screen QWERTY keypad, and the 2.55" screen may prove to be too small for some. HTC wildfire - launching in a month- might fit in ur budget but it will again be a close call. Samsung Corby i5500 - running android 2.1 with 3G, Wi-fi et al should launch soon (launching in italy in a week, should be here within a mnth), this could be a good idea. The galaxy i5800, when it does arrive, if ever, should also be a nice option if ur willing to wait

@ vijayshimla,
I've used the SE Elm and i was quite satisfied with it. The Hazel is basically the same stuff, just a larger screen and a slider form factor. keep in mind that this is not a smartphone, and its customization options will be limited. Oter than that, its camera is very good, the usual conectivity features( 3G, Wi-fi) are present as always and the keys are decently sized and quite easy to use. It should be a good upgrade to ur K750i
