Value of 3 helicopters
Looks like you've been in my basement LoL.
Well as said some of the heli's look very good, but parts availability is a must. The Kalt I have 2 of them, they are solid very well built helis. The only drawback there is parts (big one) and I'm thinking flapping head which can cause boom strikes for the newbie more easily than other helis. I have a all metal head I gave near $200 dollars for shipped for my Kalt I never used (shame) But parts are few & far in between and when they're gone thats it I'm afraid. The other heli parts is the issue...
The JR 622 is a good solid heli radio for the beginner, but as said above if cas is not an issue you can buy a radio that will grow with you as your experience level rise.
The plane looks good, check the build quality and structural soundness of it very well. Looks like a good builder, that just might of layed off for a few years.
Some of the newer 30 sized heli's offer so much more really for about the same prices as the older kits shown. I love to collect older stuff from old GMP Cricket fixed pitch (rough to learn out & outdated but I collect them) & Kalts. But for using them its a different ball game.
