depends what your expectations are.
i recently went thru the same dilemma.
if you really want to install CFW, you'll wanna hold out until you can find a decent 200x Slim which is hackable.
ideally if youre lucky enough to find one with OFW 3.55 or lower(unlikely)
or if it has 3.56 OFW or higher it will require a h/w downgrade (not recommended for technically challanged)
if this sounds out of your league, dont worry about hacking and go wit a 3xxx Slim model.
the new 4000 Super Slims are built a little cheaper IMHO. personally hate the sliding disk tray....
what the hell were they thinking?!?
