Sailrite makes a GREAT machine. I have the LSZ-1 and wouldn''t part with it for anything!!! I also purchased the large torque
wheel so I can hand spin it if no power is available. So far that has not been an issue yet, I run it on a 200watt converter from my house battery & it works just fine! The LSZ-1 is the zig-zag version, the have just the straight stich version also. I think I paid about $650 new for mine. They are at www.sailrite.com
Happy sailing!!!!
