Which pocket chinese translator?

I want to buy a pocket electronic translator. Looking things up in my dictionary is too annoying. It's big and heavy, and doesn't even have 'marketing' in it. It has Market, but not Marketing.

In class, many students have pocket translators. The best I have seen is a Sony Clie PDA, apparently with this one you can write chinese onto it using the pen.

I'm looking for a pocket translator with a pen. I saw some of these in HK - shoudl really have bought one then. I suppose one that understood both traditional as well as simplified chinese would be ideal, but maybe simplified would suffice for now. If it did do both, it would be nice if it could translate from simplified chinese to traditional chinese.

Also, given that one of these translator things will probably cost about 2-3000 rmb (200 pounds?) I need to see if I can get good software instead for my HP Ipaq PocketPC - which runs Windows CE. Actually my pda is still in HK, but I think it would be more convenient than carrying another gadget, when it comes to the medium / long term.

Not really sure where / how to look for these things, given that all of the info sources etc. are in chinese. Going to visit the electronics district this weekend - will have a look then.
