I am currently performing layout work that requires me to stake out points on a finished concrete floor on multiple floors of a building that is nearing 90 years old. It is a pretty neat project.
We have been using peanut prisms for accuracy, and either using them on the small point and running a conventional instrument, or on a 1' tall mini stakeout rod running robotic.
I was cleaning up the office the other day, and ran across this mini prism stand that I had purchased off of ebay just because I thought it might come in handy, and low and behold, it will be my rodman tomorrow. I had to purchase longer screws to make the stand a little taller to allow for the mini prism point to just barely touch the floor, but I think this should work out quite nicely.
I love it! What a great tool.
I bought one of these a few years ago, also on ebay - it was pretty inexpensive, from China as I recall.
It has come in handy on many occasions.

You are correct. I bought two more today for my other mini prisms for $9.50 each. I bought the screws Metric (M5-.8 x 60) at Home Depot this morning for $6 dollars and some change.
Total investment for each setup will be about $13.
A few more ideas!
I just remembered the last time I used it, about 2 weeks ago.
I had a tree branch in the way of a shot - a fancy ornamental that I couldn't trim.
I tried to prop it out of the way with a prism pole, but the branch would just slip off the top.
So I screwed this mini tripod upside down on the top of the pole. The three screws worked like a charm and kept the branch from slipping off the pole.
Steve,
I'd love to have one of those, but it just wasn't in the budget for this project. Do you like it? Is it worth the price?
I've seen several different models, versions when I did a google search.
Thanks,
Jimmy
You shoulda used a Plumb hammer!

Wouldn't be to me. Build your own for $27 plus $20 for shipping.
Add some threaded rod and a mini prism pole.

We have the model that has 2 adjustable legs and a point to center the prism over an existing monument. The level is large and sensitive. I have considered using it to do GPS observations on Bench Marks on bridges where you don't have room to set up a tripod without blocking traffic.
Are those magnets on that bottom photo? I can't quite tell.
Thanks.

Yes, magnets - try it on top of a bolt - works pretty good:-)

Don't forget the laser pointer, and a means of keeping it in adjustment. The latter is the thing that would concern me the most with that setup, store-bought or otherwise.
