Other spinners warned me that once I got my first wheel it would be a slippery slope towards acquiring more wheels after that. I didn't believe them. After all, I'd settled on a Schacht wheel

I'd spun on a Lendrum for a few months and it is a very nice wheel - no doubt about it. It did fold down a bit but was still substantial to transport (13 lbs). I was quite taken with the Louet


Here's the wheel folded up. There is a hole in the wheel and the frame that match up allowing you to place a screw

Here's the wheel set up before its first run. I chose some Lisa Souza Blue Faced Leicester roving in the buttery Jonquil colourway to futz around and get the wheel to a point where I was spinning consistent yarn. I'd planned on a day or two of adjustments before I was happy with the

It's been postulated that spinning's growth in popularity has come from knitters turned spinners. As The Yarn Harlot puts it "Cool! Another way to get yarn." Knitters like knitting largely because it's portable and therefore this explosion in folding/portable wheels is an off-shoot of that expectation.
If you're wavering between a Louet Victoria and a Kromski Sonata I would suggest that the degree of portability you need be your guide. If you're like my friend and travel to a cottage, camp or travel on business a lot - I would recommend the Victoria. It takes up little room and delivers a nice spinning punch pound for pound. If you have a closet or two to store a slightly larger bag and want a wheel that will feel like a full sized wheel but be more portable - the Kromski Sonata is a great solution. Louet = traveling wheel, Kromski = portable wheel.
My Sonata and I have much beautiful yarn to make. I'm looking forward to taking it to my upcoming seminar on how to spin yarn to make socks in May. There's just something extra mysterious about an import.
