I'm choosing "new" 3d scanner for our small office, stucked a bit on these offers (our budget doesn't allow us to go beyond the limits of $20k, may be +$1-2k more but it's max) - Leica c5 (ebay, used), Creaform 700 CX (ebay, used too), Artec Eva (new) or eQuality Rexcan DS3 (amazon, new, but I doubt because I've never heard of this scanner). Can you give any advise pls if it's not hard for you? I know that buying used tools is kinda buying a cat in a bag.
