Your link to the Peak LCR45 is more expensive then the DER EE 5000.
I would not even consider buying that toy myself.
What sort of measurements do you want to make with your meter?
If budget is really such a constraint, you are probably better off by starting with the transistor tester, and if that is not good enough, it at least buys you some time to save up to get the DER EE 5000.
I started some 15+ years ago by building an LM311 based LC meter, because real LCR meters were too expensive for me. This meter worked quite good, but with no other reference, I could only compare it with the values printed on inductors itself, but they always matched close enough, and series connections of inductors also turned out correct. Later I added a few of the "transistor tester" gadgets to my equipment and both meters agree with each other close enough.
I was tempted to buy the DER EE 5000 when it became available. It's quite reasonable in price, and performance is comparable with meters twice it's price. I'm not on a tight budget myself, and I could easily buy it now, but the simple fact is that the combination of the homebrew LM311 meter and the transistor tester is simply good enough for my purposes, and that is the only reason I never bought the DER EE 5000 myself.
