I am managing without one as well. My friend has one that she got at a car boot sale for almost nothing, so I was really jealous as you can imagine (!). Luckily she is really nice and now pregnant so I will be able to borrow it for a few months! I have never used one so I will be interested to see what I have missed....
It was JK Trading, and I see they are starting bids at $159, they are based in Sydney, I can't remember how much postage was, I always get a quote. Occassionally they put one up for a low starting price, that's how I got mine so cheap - so keep an eye out. Having a look on Ebay there is certainly alot on there, most for local pick up only though, sigh. Goodluck!
I found my mannequin brand new (but technically second hand) from the online Gumtree classifieds. If you wanted to have a look the Brisbane Gumtree classifieds can be found here. My mannequin is the type they sell at Spotlight but I got it for $100 instead of $350.
That said however, I've had some issues with fitting using mannequins. My mannequin is the standard type with dials at the neck, bust, waist and hips - it isn't one of those super adjustable ones with dials all over the place. As a result, my mannequin's shoulders are 2" narrower than mine (so bodices never sit right) and I'm tall so my waist is around the area of my mannequin's hips! So I'd recommend comparing your measurements to the non-adjustable parts of the mannequin. But maybe there's a way around that stuff? I really don't know!
Thanks for that - I will have a look at the classifieds. Maybe you can pad yours our a little in the shoulders so they are closer to your size? I have no solutions for the waist though!!
My mannequin sounds like it could be similar to yours. It was from a sale at Lincraft years ago. I can change the waist length though. Forgive me if I sound silly for suggesting this to you.. I'm sure you've had a good play with it, but I thought maybe getting it secondhand you might not have had the instructions. Have a look inside the mannequin. The torso on mine can be slid up and down on long pins - this function is not obvious from the outside and is a bit fidly, you have to hold back some lever like metal bits and shuffle the torso to where you want it.
