are there any that are recommended for Industrial Customers?

I would recommend www.worldinfodata.com .
They have 14 Million US Business Database, 220 Million Consumer Database, 1.4 Million Canadian Business Database, 2.3 Million UK Business Database, over 1 Million Realtors Email Database, Dentists Email Database, Doctors Email Database.... and more
Their price is really cheap , just 1 c ent per record and you can request free 1000 records to test the data. Their serive is also as good.
