Oh I am with all the other enablers, could not do without an overlocker these days either - so yes go for it.
You may think I am absolutely bonkers, but I overlock all my toile fabric pieces once they are cut out, with all the fitting and adjusting I have to do, I cannot stand all the threads working loose and dangling and getting in the way, at least by overlocking all the edges it remains neat and tidy.
Whilst I have not actually started using knit fabrics, I am ready to do so, only the need for summer wear has pushed the sort of winter wear on to the back burner. Now with what I am about to start sewing is some shoulder princess seams, and on the toile somehow the usual 5/8" seam allowance despite being clipped it is not looking right, so I am going to try and press the seam allowance to one side and then trim it down and overlock this - so this looks like more ready to wear seam finishing than the usual pressed open seaming.
I am lucky in that I actually have two Bernina overlockers, the larger one will actually do coverstitch, chain stitch, overlocking and possibly some other stitches, whilst the smaller one is just an overlocker.
I actually went on a course when I bought the smaller overlocker, and whilst most of the group had a Bernina, there was one that wasn't and this made such a racket it was quite disturbing and it also bounced around a lot. Whilst my Berninas are much quieter they are solid machines and stay put no jumping around. My very first overlocker was an Elna and that was a lovely machine, but after about 10 years was causing a lot of problems not stitching properly, stinking the house out, and as I was making my daughter's wedding dress at the time, I had no choice but to go and buy a new overlocker just three weeks before the wedding - and oh what a difference this new one was - yes the smaller Bernina that I have. This is now about 16 years old and has never caused me any problems at all.
When I first bought my smaller Bernina I had the opportunity to buy a pack of 5 additional feet at a ridiculously silly price, bought separately they were around the £30 each. The five attachments are a Multi-purpose Foot with guide, a Blind Stitch Foot, a Gathering Attachment, a Cording Foot, and an Elasticator.
I believe but am not at all sure that it is Juki that manufactures the overlockers/coverstitchers for Bernina, but worth checking out. I know that Bernina have a very strict guidelines that have to be followed when these machines are made which is not a bad thing.
Go on take a gamble I think you will just fall in love with one, and with you intending to make more clothes for your little god-daughters you have nothing to lose Perhaps in six months time you will be back on here saying you didn't now what you were missing.
