Yet another resistance decade box
Fortran:
I second what Peter said.
It's never going to be a high-end product. But with a new board it's probably good enough for most hobbyists.
It will definitely be good enough for most beginners!
And for the price of 1USD for 6 boards, complaints isn't an option.
I've poured a few hundred bucks into this already just because I like the idea, with basically zero margin. If I don't sell enough of them I'll loose money.
If you want a professional device, spend the extra 500USD or so and get one.
This is basically putting makeup on a pig, and should be treated as such.
But for what you're paying.. it's quite an attractive pig :)

they make larger style thumbwheels.

Indeed they do, but ten KM2 switches cost me about GBP 4 delivered. Larger switches from recognised suppliers and distributed by Farnell in the UK are around GBP 20 each

At GBP 120 just for switches on a six decade box such a project would be a non starter for me especially when I could buy a significantly larger form factor one fully assembled and off the shelf for GBP 100

or for those with much deeper pockets an IET Labs one for GBP 600

or a Time Electronics one for roughly the same GBP 600

linux-works:
I understand the original motivation and yes, after 4 pages and talk of group buys, its gone beyond one guy who has a surplus of parts he wanted to get use out of.
that said, if people have put money in, it would not be fair to leave them; and so I would continue to support the project and buy my reserved boards so that the organizers don't lose money.
bitseeker:
Yep, I like this little one because the size and cost are good for tinkering. I got a used IET box for long-term, "serious" use (and higher wattage). It's all good.
all_repair:
I am going to throw a few into my site-work bag, and a few in the lab when testing some process meter. Save me finding, filing or buying loose resistors for setup need. Yes, I do have a tank-like decade box.
