I agree, VPI makes some great equipment. However, its current machines are old technology. Ultra sonic is the newer technology and does a much better job of cleaning. So while currently ultra is more expensive, it is the future. No special fluids needed. Rumor has it that Harry is working on his own version of ultra. Those efforts will be a challenge as the patents for the technology in place a very strong. So, if you want the best, beyond VPI and Keith Monks, go ultra. Any don't forget the steam.
