That Tenma station from Farnells is just a 'clone' rebranded for them, or so I have read in the 'other equipment' forum.
Just search for 'soldering irons' in that section for lots of views.
Have had some Tenma meters and never been that keen on them and also bought a different brand low cost solder station from Farnells some years ago, extremely poor quality.
As far as I can see, in the UK / Ireland ( south ?) your choice is basically the 936/937 solder stations clones in various guises, or then go for a genuine Hakko FX but that cost £130 delivered; way too much for a beginner imo.
I did try a cheapo Chinesse temperature controlled iron , again, some years ago, but that just ran way too hot .
Bear in mind that standard mains iron do tend to run a little hot if left On in the stand for too long, and as such would not be helpful for production work, however for basic diy work , even down to smd work, you know of these little limitations and its easy enough to work with them imo, though sure that will bring many comments !
As for the Antex adjustable one, never seen one so hard to say. I have found the standard irons extremely reliable and very handy for field work where a bulky station is impracticable.
Hopefully someone else who has one can comment on how good they are, though at £60+ thats lot more than 2 standard irons ...
As for books to use, cannot comment other than to say, follow one that you find easy to get on with.
Perhaps do not be a slave to just following a book, do also try you own little projects / practical experiments alongside the theory.
You do not say where your particular electronic interests are, but there are many sites for various projects, from the 'simple' 555 timer up to microprocessors that you can try out now.
