Is it a bad idea? Would you be put off buying one? I'd almost made up my mind to get a Brother BC2100, which seems really well-liked with great reviews, but seems to be no longer manufactured (a fairly recent development). I'm also considering a Janome 525s. Not sure what to do.
I think over time most models of machine are discontinued. Often the parts are interchangeable. If it's a shop you are buying from, ask them what the spares/repairs are like. My machine is ancient, but most parts are standard, I have a local shop who specialise in repairs and he's been brilliant when it went a bit squiffy.
Mine was an older model when I got it, as long as it's a good model from a reputable company you ought to be fine. I can still get different feet and accessories for my machine (now 10 years old) as these are all standard.
Thanks for the opinions. There is a very reputable dealership & repair centre not too far from here, so I'll go and have a chat with them. My current machine (Elna 2007) is a pain in the bum - don't want to make another mistake!
