Honestly, none of those domains are good. RSSTECHNET.com - can't see any value MSTLIVE.com - same SAFBE.com - Just a random LLLLL.com, many are still left with better letter combos IMO. I'd say reg fee. v6tech.net - Don't get it, $0 DamnINeedABeer.com - Brandable but long. Would need development to be worth more than reg fee.
