A i stated in another post, i have a basic machine that cost about £80 a few years ago. It's done me well for the basics, but recently i've had a problem with some of the stitches on it. When you select a stitch, it does'nt seem to be doing the stitch you want.
This could have something to do with the tensions and stitch sizes, i'm not sure, however i do know that i hardly ever clean the thing.

A quick rub over with a baby wipe is about as much as it gets.
I asked in a nearby sewing shop and the guy said he charged £40 an hour to look at it, plus parts. Sorry but in 2 hours i could have bought a new machine!
I just took a look briefly on the net and there seems to be a few sites that tell you how to clean the insides. I wondered if any of you do this or do you get yours serviced/fixed at a shop?
Thanks,
Calv.
