Get it! I have one and it rules. Make sure you also get the Portapros that came with it! As for the amp power... The manual says "more than 50mW at 32 Ohms". It really does need an amp to get the most out of it though.
Also the hard disk is fairly easy to upgrade if you're handy with a screwdriver.
The biggest downside is the transfer speed. It's about as fast as a snail running through molasses in a blizzard. It took about 48 hours to load 20GB into mine. However, the capacity is such that you don't do mass loads of that size very often.
The other downside is the volume is digital. To get the best sound out of it it needs to be at full volume. That's not so great for the ears on most headphones. Because of this I use an amp. I just crank the volume all the way up and use the amp to keep the volume in check. This pulls the most details out of the music.
I honestly couldn't be happier with mine and will upgrade it to a 40 GB drive soon. I figure once I grow past the 40 GB drive better options will be available, but that's a year or two away.
BTW, the DAC is a Crystal 4332 I believe and the op-amp is an LM4880. There is no line-out but adding one shouldn't be too difficult, though it will void the warranty.

BTW, don't listen to the ppl that will tell you it sucks becasue it's an MP3 player. They are just jealous.
