depends what you're comparing it to.
if you're comparing to similar sized wanhaos or flashforges(it's a rebranded flashforge) its not that different in price.
if you compare it to makerbots it's a bargain. and less bullshit than current mbi products. and just as capable (PLA only like all current makerbot printers).
as to why having ability to print abs is sometimes nice: it can withstand higher operating temps for the part you print. 60 degrees(hot car) and pla gets easy to deform.
as to why cheapo printers don't allow for abs.. you need at the very least a heated bed and that needs better PSU.. and an enclosure helps too.
for a thousand bucks with a brand name association and warranty it's no really so badly priced. of course if you can tinker a little bit you can get a printer for 500 bucks - but be prepared to spend couple of weeks tinkering around getting it just right. my currently in use printer cost total of about 540 bucks with the upgrades i had to do and it prints now ok(comparable to 1000$ printers) but it took redesigning of some parts to get to this point.
point being, you can buy makerbot 5th gen for 2800+$.. or you could buy two of these and forty kilos of plastic. and the 5th gen probably needs you to call support more often (mbi just recently killed their google support group to cut bad press. among other things their new smart extruder is a _mess_ and not user maintainable, so you have to send it back every time you get a clog - which is quite often since they fucked up the redesign real bad).
and the flashforge dreamer or dremel rebadge of it seems to have a lot saner approach when it comes to stepper motor driving too(mbi rolled a custom stepper driver solution for their 5th gens.. and it's noisy as hell and the board seems built so that it is non trivial to update the sw on the driver chips)..
