I play electric guitar but find that I'm at my girlfriend's mostly who lives in a small apartment. I've had on my mind to buy something portable like the PX5D for noodling around via headphones but would like something that will also record, like my rather old and relatively large Tascam Portastudio Cassette Recorder.

My friend has shown me his PX5 and he's also got a Tascam DP-004 but between the price of those two, it's approaching the price of the Boss BR 800. So my question is, is it better to buy the BOSS as an all in one unit and does it have a "phrase trainer" equivalent like the Korg?
