Does anyone here use the Peak Lcr45? Max Inductance?

I had planned on buying a DE5000 LCR meter, although I had my eye on the LCR45 too. The more I read up on the DE5000 the less impressed I am with it. Apparently it has a horrible user interface. I also want to be able to measure impedance (Z real and imaginary) and the DE5000 does not display a Z value on the screen. Apparently there is PC software for the DE5000 which will give you impedance measurements and all kinds of other cool data. The problem here is #1 you have to buy a $70 cable that seems pretty hard to source or you can DIY a FTDI and phototransistor for much cheaper but without a 3d printer the adapter would turn out physically pretty janky. #2 is the bigger issue, and that is, that the link for the software on DEER EEs web site is broken and I can't seem to find the file download anywhere else. Then I realized the LCR45 actually measures at 200Khz vs the DE5000s 100Khz. The only issue I have with the LCR45 is its form factor and built in test hooks. I have a cart at Amazon full of stuff I need including a new bench supply but I haven't pulled the trigger on it yet because I have not decided on whether I should buy the DE5000 or the LCR45.

I was just about to complete my Amazon order with the LCR45 in cart, but I realized the listed specifications say the max measurable inductance is 2H. I would like to be able to measure transformer windings, and 2H wont cut it for any sizeable power transformer. I read the LCR45 User Manual, and on page 17, it says at a 1khz test frequency you can measure up to 10H. So can this thing measure up to 10H or 2H?? I e-mailed Peak a week ago with this question and have not gotten a reply. Im hoping someone on the forum who has an LCR45 can clear this up for me.

Study this thread and particularly its conclusion:

Im sorry im kind of confused, that thread seems to be a comparison of different LCR tweezer meters and there accuracy?  I read the first and last two pages, if there was something relevant to my post i either missed it, or it went over my head, either is very possible.

Im just trying to figure out the max possible inductance the peak lcr45 can measure, becuase the listed specs and the user manual differ.  Im not sure if im just missing what your trying to get me to see in that thread? I dont want to use this meter for very much smd stuff, and i try to never make in circuit measurements of component values. Im just looking to get quick measurements of through hole inductors and caps for low freq non RF. Im not even all that concerned with absolute accuracy as long as im in the ball park. But being able to measure transformer windings would be super helpful sometimes! I deal with a lot of transformers that have to documentation.
Psi:
I have the older peak LCR40.
I can test anything on it if you can think of something.
Presumably if the LCR40 can do it the LCR45 can too.

I have a good selection of mains transformers if you can think of a size/amps rating one you'd like me to test.
J-R:
I have the LCR45 and it goes up to 10H in the 1kHz setting.

Side note, the LCR45 is annoying to use, so get the DE5000 as well.
