i have a procut mini and procut dry xl and know people with a centurionpro and t4 twister
both procut machines are really quiet machines and can be used in the same room while your doing other things while with the CP and twister, you better have some good ear plugs, they are really noisy
the only downside is powered procut trimmers are advertised as having usa made motors and when both motors broke, i took off the back panel and noticed it had china made motors, been trying to get some sort of warranty since sept but it hasnt happened yet, it was quicker to order a china motor than wait for procut
edit - i paid roughly 2500cdn for it and it has paid for itself, i've probably ran 300lbs through the smaller machine and probably saved 10k by only having to hire trimmers for 2 days, if things go south with it and i have to replace the drum, i will look into a centurionpro dbt trimmer
