Quoted for emphasis -- that was meant to be a question, I.E. what is your budget? Also, what is it you're trying to record?
And yes, at this point, there is no reason not to go flash-based. MiniDisc was a good budget entry point at the time, but nowadays, flash memory is cheap, and therefore so are the recorders.
There exists a portable DSD recorder -- I intend to have on in my stable before I'm done. I'm guessing (entirely) that this will be one of the better sounding ones. Also, whether or not you intend to record anything beyond stereo is important (there are a couple that can do 4 channels).
Also: H4N advertises itself as doing USB 2.0 -- which implies that there are others besides the H2 and original H4 that don't -- just make sure you check.
