There are few things I look for in PDA RSS readers and that is speed, options, wi-fi sync & images. (Oh and it being free

)
That amounted to me getting AvantGo & Mobipocket somehow.

and recently Mobipocket failed me on the images and BT sync with the latest release and Avantgo always seems to be missing data and looping with the wi-fi sync which is abit turtle-ish...
I saw mDigger about 3 weeks ago but I just overlooked it as more of the same but finally I said what the hell. I must say it adds up all five things I was looking for. *Still I wonder if I can add some unlisted channels* I was suprised to see so many, so much so, now I'm only missing 3 channels: Softpedia, Aximsite & Yahoo's mobile tech rss.
Might be old to some but if all of what I said in my 1st sentence, fits your bill, go for it.
