Well, I currently own an RG350.
It is a very fine guitar, but I WANT (I want, but I dont need

) something better.
I am currently looking at 6 different guitars:
The RG1550/1570
The RG3570/3550
The RG2550/2570
The RG770DX
The
Jackson DK2M
The ESP Horizon II FR
I live in Portugal, our currency is in Euros, but if I buy one of these guitars, I will order online, most probably from dv247.com
My dillema:
Should I get the RG1550/1570?
It is relatively cheap, (700 euros or so, on guitare playback).
It has a Basswood body (The same as my RG350), but it has an Edge Pro, and is a Prestige guitar.
If i get this guitar, I will change the pickups to a Air Norton / Tone Zone Combo.
The RG2550 (I can get this for 800/900 euros)
The same as the RG1550/1570, but it has DMZ/IBZ pickups, a different neck, and whatnots...
I would change them to the AN/TZ combo too, so I guess the RG2550 is a NO GO.
(I would be paying more and I would get the same)
The RG3550 (I Cant find this guitar for Sale in europe ANYWHERE

)
This seems to be a very fine guitar, and GUESS WHAT? It already has the Air Norton and Tone zone pickup combo, so that eases things up a little bit

But it has the Edge0, which a ton of people here seem to hate...
The ESP Horizon II FR:
I know it isnīt an
Ibanez guitar, so dont kill me
haha, I simple love the body, the neck, it has some fine pickups, ORIGINAL Floyd Rose, it is Japanese made, etc...
It costs about 1400 euros, it is a bit expensive, but right now, I am looking for a "High-End" guitar that will last for the rest of my life, so I guess that getting this would cut the GAS off hahaha
The Jackson DK2M:
It has an Alder Body, Seymore Duncan Pickps, Floyd Rose (dunno if it is a licensed one, or a original), People say it has a think neck, etc...
It costs about 500 euros NEW... it is the cheapest of the 6 guitars that I posted, and it has some very fine specs...
What I am looking for in a guitar:
Kick ass playabilty, Nice sound, great sustain, thin neck, etc... (low action?)
I know that the price range is very different (500 euros to 1500 lol), but I am looking for something that is Good, and fits my needs.
The RG1570 seems to be a very fine guitar, and with the AN/TZ combo, it will probably be at the same level as the ESP, no?
The RG2550 seems to be a fine guitar also, but I guess that it is not worth it
The RG3550 seems to have all that I want, but It has the Edge0 tremolo that every one complains
ESP: haha lol, is it worth it to shell out 1500 euros on this guitar???
Jackson: Price vs Performance king?
Well, sorry for such a long text, I hope that I used acceptable grammar, etc... thus I am Portuguese, and, well, English is not my first Language.
Thank you for all your future answers, I hope that this is just GAS speaking, but I will probably end up getting a better guitar than my RG350 somewhere in a near future, and I dont want to have the feeling:
"Damn, with x Euros more I could have something much better..."
