Electronic Japanese Dictionaries

Are electronic Japanese dictionaries really useful? I'm still debating whether I should get one. I'm confused as to which ones have English menu's. I keep hearing about "Canon Wordtank G55", it doesn't have the option to draw in the kanji with a stylus, I was just wondering if it's troublesome to look up kanji without it.

Here's the cheapest place I've found online FYI

OP back

I narrowed it down to these two

and

I have decided on the XD-GF9800 because of some reviews that I've read [and didn't bother to bookmark]. Now I'll do research on where to get this model the cheapest and if it has English menu's.
