Looking for feedback on the following MD machines. I've been I the biz for 7 years but just went out on my own. Want to add microderm to the list of services. Price points are from 1k to 4k just wondering if I go small or go big.

Looking at:
SkinSmoothPro
Silhoute-Tone Silver Peel
DiamondTome NewApeel Petite
SatinSmooth DermaRadiance

I've used the DiamondTome equipment before ... Just wondering if I should take the jump. Thank you!!
