if you're ever looking for reviews of gear then check out sound on sound magazine. it's much more in-depth than future music/computer music....bit more of an industry mag - well written but a bit dry sometimes. they know their stuff though.
if you want an all in one type jobba it does seem well rated...not played on one myself
obviously it depends on your budget but if you do want to go the hardware route then I'd personally go for an akai mpc (as used by tom n ed live and legions of hip hop producers) for sequencing and get a hardware synth for synth sounds etc.
all in one boxes never seem to cut it for me.
however if you want something for a first forray into hardware sequencing this could be for you. your best bet is to go in to a friendly music shop. explain that you're serious about a purchase and ask to have a play!

the day I had to sell my mpc to pay the rent was just about the saddest day I can think of.....no wait, the day I had to sell my bass guitar was pretty dark too :(
