Will's advice is sound in that an experienced eye looking over you and any prospective gun would be worthwhile.
Spending a few quid on a lesson with a good coach would pay dividends before you purchase any gun, they will ensure that the fundamentals of appropriate posture and stance are there and that can transform what feels like an ill fitting gun into something that is spot on.
A good coach may also help you choose a gun too and give peace of mind.
The review in the link that you posted was for a 20b so very likely a lighter weight gun so don't be too put off.
I would say that don't set out to try and buy your perfect gun now, if you happen to find it then fantastic, but it is reasonable to assume that after a year or two your thoughts may change as your skill and technique develops.
Most important of all is choose the gun that makes you happy, don't stress about the opinions of others as what might work for them does not mean it will work for you.
If you are happy in your choice you will shoot better with it as so much of this game is confidence.
The Fabarm is not a bad choice, the looks are a bit marmite and they are fairly rare, but that doesn't make them bad. The quality of manufacture is good and if you point it in the right place it will do its job.
Being right for you is more important than the label or resale value, after all if you shoot it well you aint gonna want to get rid.
As mentioned many times fit is important, if you can get a wise head to watch you shoot it along with a few other guns that will be way more valuable than a magazine review or opinions on a forum.
Also be warned buying guns is addictive
