Early Birthday present

I have wanted a serger/overlocker for years but have never got around to getting one. So when my husband asked what I wanted for my birthday I had just seen this, so thought this was the time to get one, particularly as I couldn't think of anything else that I desperately wanted. I had the choice of one model, but it's a Singer so will be able to get spares world wide. Now I just have to figure out how it works. The instruction booklet doesn't look that user friendly. Oh well thank God for U tube!
