i use many small suppliers quite often. i stuck with Lincoln for the bulk of my orders because i have a long standing relationship with my rep there.....sucks that zahn had to scoop them up. it does make it hard and some of my business is back on the market.
ive used nowak some (not much and not recently),us dental depot, dental emporium, pearson, canyon state, and a handful of others.
a lot of my hangups with little guys is shipping.....time and cost. shipping is already a huge burden via cost, and it only gets worse when things take a long time to make their way to the lab. pearson and canyon are too far to make reasonable purchases so i only use them for a few items that only they carry.
us dental depot and dental emporium have a bunch of my monthly items for about 50% less than zahn does (shockingly) listed on ebay...so they get that business. and nowak, its been awhile but i keep hearing good things. biggest issue is spending the time to sift through the website and decifer their item listings vs the normal items i buy and make my order. they dont correlate so its time consuming without a catalog. time is a precious commodity right now, there is not enough to spend doing that, this was my 5 min break for the day. back to work! lol
