Sewing Machine !!

Well my mom had bought a sewing machine (Singer) that was supposed to be refurbished and on display, that was some 4-5 years ago ! That was a nice investment, supposed to be a fashion machine, that can do embroidery etc .. well interesting enough, that was for 5000/- , and it was pretty advanced. The salesman seems to have convinced my mom, especially when we see the difference between the original price and the sale price, it seemed like a steal. She did have a decent hand sewing machine, that has been working flawlessly for the past 20 years !
Now the true woes begin, it was a huge struggle, it kept failing and failing, finally my mom spends about 1500/- per year to maintain it .. (sometimes more). Sometimes that makes me think, refurbished products, sometimes don't work well ! or is it always ?

Here is what i propose, she should buy ..its a 2200/- USHA machine ! Simple mechanical sewing machine !
