The Singer 99 is a 3/4 size machine with full power. Parts can be bought very reasonably at
http://www.sew-classic.com/ - the owner is wonderful. I buy parts also on ebay. Plain, clear, good sewing machine oil. Clean the machine real well. Some other helpful sites are: the Vintage Singer sewing machine blog,

You can buy a 3/4 foot for quilting and other feet from these places, replacement bulbs, etc. There is a lot of info on the 99 on the web. I bought one and two Spartans (stripped down 99s). I am converting one Spartan to a hand crank. A good sewing 99 can crank through a lot of fabric evenly better than the "new" machines.
