I would look on ebay for those machines ppl buy.. or husbands buy for them and then they dont use them! Which that budget, you could get a very very good machine that could have been 4-600 new. My personal favouites with machines are bernina pfaff and husquvarna, not saying that no other brand is any good, they are just the ones I personally prefer
the machines that I use day in day out are a 30 yr old pfaff, a 17 yr old pfaff, and a brand new bernina. My two pfaffs are lovely, they have been loyal friends the first one since I was nine. Nothing has ever gone wrong with them. Older and new machines, especially German and Swiss machines just seem to have been on the top of the machine leaderboard for years and years. New cheaper machines, well the gears are plastic, the motor wont be as strong, so not quite as much "punch" as a more expensive machine. Secondhand more expensive machines are like cars, as soon as you take them out of the shop they lose money. But, the cheaper the machine was in the first place the more it will lose. A more expensive machine, people know will last them, and the people that buy them look after them generally, better than the cheaper ones. You could get a 4-7 yr modern bernina for the budget your talking about, and it will last you a lifetime and may become your best buddy
I did have a thread going with good ebay finds( ie machines!)... in all budgets.. I'll go have a looky tonight and update it and put the link for it in here
