The 1000 and the 800 are very nice but to be honest not worth the money unless ur gonna use the full selection of tricks. Most clubs have 100s, or 500's anyway so most stuff your used to in ur room u won't be able to do when ur out.

u could take it with u but again the 100s are small compact and get the job done.

yeh, but is the pitch as acurate as that on the 800 or 1000. This has to be the most important factor when mixing.
