I can't help you with that model but want to mention an alternative to consider.
After using a TX and a LifeDrive, I've downgraded to a second hand Zire72. It's an older model with a smaller screen and a bit less memory, but it's still OS5.x and high resolution 320x320, has all of the features of the more fancy models (except wifi), plays my lesson podcasts, takes low res photos and videos (handy for chinese signs, book pages), fits in my pocket without making it sag, can use an SDCard up to 2mb, pretty stable, and runs Pleco nicely.
You can pick these up very cheaply second hand (try ebay?), because the blue paint peels off after a few weeks use and they look disgusting, nobody would even want to steal it! Yet behind the yuck they're often as new. Cheap enough to try and throw away if you want something better, so you have nothing to lose. Get a hard case for peace of mind if possible, and you won't notice its chewed appearance much.
Maybe I'm odd, but my expensive fancy TX lies idle while I use this versatile little gem constantly. Not just any zire, it's gotta be the z72.
