Just get a fun club together! half a dozen guys can share the cost of one machine. The guy that paid the most gets to use it last after the rest of the gang have unloaded into it- also saves on lube!!
Being a satisfied owner of a Venus, I can vouch that they are merciless and pleasurable to the point of torture. I've pushed mine hard to torture my baby batter from my balls three times in succession. It left me spent and my balls aching for more several hours later. So yeah, worth every cent guys.
