My Elna Super C62, purchased in 1972, died a little over a year ago, 2010. The bottom line is that Elna/Elna America does not support that particular old machine. The head of the "factory repair" section in the US told me there isn't even a repair manual for it in the US. My Elna and I sewed draperies, clothes for our children, clothes for my husband and me, 10 years of drum corps uniform alterations (about 120 a summer), drum corps flags for the color guard, drum corps color guard uniforms, repairs for the tonneau cover of my husband's MGB, darned my dad's work jeans, did free hand embroidery, you name it. When it died it sewed every bit as well as it did the day I tried it out at the dealer's. I was heartbroken and must have been pitiful.
Since I don't do being sewing machine-less gracefully, during that year I bought and inherited several other machine: Singer 99 (treadle, my grandmother's), Bernina 1630 (computerized, maybe 18 years old, the identical twin of hers), Singer Featherweight II (goes in the RV), Singer 403 Slant-O-Matic (my other grandmother's). Surprizingly, all of them are still supported by their manufacturers. Parts are available. The only problem I've had is that the local dealers would much rather you get parts and pieces for the Bernina 1630 through Bernina. (Or of course, buy the latest, greatest Bernina top of the line, from them.) The dealers will order 1630 stuff for me but can offer no sewing advice or clarify the owner's manual. In some places the manual is a real puzzle. Please note that all these sewing machines do a really fine job of sewing - no kidding - and with the exception of the Featherweight II, are all over 15 years old.
No matter what you finally choose to sew on, for heaven's sake, pick one that is supported by the manufacturer and that has a really good, HONEST, dealer offering excellent service. (It helps if the dealer is in your vicinity.)
The end of my tale is that my daughter owned the next iteration of the C62 - everything the same with the exception of the thread take up lever. The lever on hers is not threaded; it has a sort of hook arrangement. In return for making draperies for her house and doing never ending clothing repair, she turned her Elna over to me. She hasn't started collecting - yet.
Good luck and please let us know how your search turns out. It's safe to say, we're on your side.
