DIY with a LZ1AQ loop amp. I'm not opposed to building my own
That's the option I would go for.
The ready built amplifier is very good value of money, and as you can remotely select different antenna combinations, it's an ideal basis for further experimentation.
Chavdar's excellent webpages have loads of useful supporting information.
Otherwise from the list you have chosen, I'd go for the Wellbrook, and wouldn't consider any of the others.
