Taking your time and doing a good job of cable management is more important than spending $90 on a set of individually sleeved cables. I frequently use the 380w Antec EarthWatts in my 'hobby' builds (latest was a Thunderbird Slot A build just for the fun of it) and with a little patience I've frequently ended up with a completely bare-wire PSU along with several ribbon cables looking better than just about any quickly-thrown-together high-end setup.
TL;DR: Spend time working on your own cable management skills instead of throwing money at the PSU and hoping it disappears.
