yes, not only due to budget restraints, but many of those machines are sold as used because they left the warehouse! Some may be show use models, you just never know! Also during the Surge of sales during say 1995-2005, every woman who had a 401K or retirement fund bought one thinking she would retire and become a quilter for money! Most found out that they were not physically able to do it, the rest found out during the market dive that they could not make a business out of it! SO, the market is now flooded with "used" machines!
IF the person used it for a business, and has 10,000 hours on it I might say NO.....
Also know what the machine is, research that make/model...many were made during that peak time frame and have flaws in general!
