well he said he wanted to make beats using records well he can go with the motif6 like helix said it has sounds and can sample, with a sequence, or you could get some thing used i.e. an asr-10 or eps-16 plus, or even a motif used off of ebay, and if you buy somthing like the asr or eps off of ebay it usely comes fully expanded with some disk, then he could buy him a sound module and some drum sample or sample them from records and that should help him out
so a estimate cost would be
Asr-10
600 at the most seen higher
sound module, 100-1500 dollars
monitors, he could get a package for about 170 to 500 dollars
drum samples ???????
zip drive to save you beats and samples
eps-16+
highest i would buy for is 250-300 dollars
and the rest same as above
motif-6
1500 dollars get it lower probley on ebay
monitor package 170-500
and some records, got sounds and stuff in their so you straight
but you have more options than this, these are just some examples, also if you lookin to sample either get a phone pre amp or get a dj mixer and turntable to.
hope this helps.
