Try Allied Electronics. They are pretty good at shipping same day.

I made my own decade box for just about any combo I could ever run across. I'll take some pictures and post as soon as I can.

I also carry a commissioning tool, made by Johnson Controls I think, for the same purpose.

You may want to just buy bare thermistors. I got 100 10K type 2 for less than $25 some time ago. They come in handy for temporary use.

Here is what I made. I have ranges for everything.Attachment 353411Attachment 353421

This is what I use.
