Anyone thinking of purchasing this should research the interwebs for the pros & cons so you know what you're getting. If you do decide to purchase it I STRONGLY recommend completing the modifications as it will make the machine a whole lot better. I ran the machine both before and after the mods - no question they NEED done!I give it 4 stars for a couple of reasons:- The makers know about the issues and have done nothing to improve the design and the major issues can be resolved for less than $10- Which is the other reason I give it 4 stars. Pretty cheap & easy to make it a really nice machine and if you're purchasing this you most likely have the skills, tools and knowledge to fix the problems.
