You may or may not have a tough time getting new parts in the event your juice breaks in the future. You understand how appliances are, they are usually one time buys due to the fact that individuals expect these to last permanently - and some do but always. People are different, and if you get attached to your juice extractor you will want to resurrect it. All the smoothly running infrastructure and processes will be in place and will tend to be easier for you with the larger companies.
If you like pulp, fine, however, not everyone does and some juice machines are designed in certain ways. For one thing, look at the specs for how a lot juice you'll get and the amount of pulp is ejected, etc.
It could be the case that too much collected pulp will make your extractor much less efficient, plus it is just one of the small nasty things about using juice extractors. Find out whenever possible on any extractor that catches your attention so you will discover all the little nuances of it.
You know that blenders make some noise when they're running, well... juicers do the same thing with a few being less noisy than others.
Search for ratings and reviews that address this issue, and it is an issue with many people. If you live alone then it's really no worries, but your situation may likely be very different. Or you can request the store you're at to let you hear one in action, so that's constantly a possibility.
