WallyTools and WallyReference

[Famester V1]

I am waiting for delivery to upgrade from my current VPI Classic 2 to VPI Prime Signature 21 in rosewood.

I used the standard tools (with the exception of a good tonearm scale) that came with the VPI Classic to set up the TT.
I saw that the WallyTools had received a good review on Stereophile magazine from Michael Fremer. I looked thru the YouTube videos and it seems like a fairly basic tool, which back in the day I probably would manufacture something similar to work.

But now, I just buy the item.
I wanted to know if anyone had experience with this or a similar tool to set up a TT and how did it go? Obviously Mr. Fremer likes the tool and has extensive experience in setting up a TT. So, if he likes it, it should be good, but $300 for a simple part like that seems extreme.
I just was hoping for another opinion before I order one.
Thanks in advance,
Fred
