The Pfaff 230 is not an industrial machine, however it is not uncommon to see Pfaff 130's mounted in industrial style tables. I have never owned a domestic Pfaff, but they are well regarded and known for being heavily built and standing up to abuse. Parts will be readily available. The price is high for that Pfaff, you can get a lot more for your money in Ohio, with just a little patience.
If you have room to spare for an industrial, and already have a lighter duty machine, I would go for an industrial. If you want another machine later (an upgrade perhaps) it's nice to already have an industrial table and either a clutch motor you like or a nice servo. Industrial machines are frequently sold as head-only units, so if you already have a table set up, and find a good deal, you can buy it and swap out heads as needed (or sell your old head).
You should wait for a better machine.
