Im considering buying a Hawk Thunder set up..Currently I have a 3.5 Vivace,3.5 Bishop,Dan Kubin Mini Cranker and was wondering if anybody owns the same machines I do and can give me any type of feed back(compared to the Thunder)..Im really curious to know how well your able to line with the Thunder and if it is really a 1 machine does all..In theory it seems genious to have 1 machine and just switch out a needle head..but sometimes theory and real world are a little different..I dont have the money to just buy a Thunder and give it a shot,I would need to sell a couple machines to be able to make it happen..so before I put some machines up for sale im just curious to hear what anybody has to say.
