Heya
Right well, you are trying to buy a guitar in the £50 to £150 bracket, this bracket is based around beginner guitars, if you want one that will last you a couple of years i will get as cheaper one as your happy with, as all you need it for, is to learn the basics of guitar, ie
Mjr Minor chords (E, A, G, C, D etc)
and a bit of single string lead work
How long have you been playing for cryptex?
If your skillfull enough and your on the next level, i would save more money up and look around the £200 - £400 pound bracket (double it for dollars)
Practice guitars will never be a guitar god thing, but do you really want to splash out soo much one a guitar when your only a beginner, start of cheap, get a niceish £50'r, then when you feel your ready buy a nice flash one that will last you a good few years!
Sum it up!
Beginner = Spend as little as you can, and get one that you can just practice on for a year or so
Intermediate = Spend around £200 - £400, this will keep you happy for a long long time
Expert = Buy one that rocks your boat in everyway, usually you only get to this stage after about 6 years of playing
Personally i have been playing for around a year and a half, i can play, Hard song (involving solos, lead, chords, rythmetic strum patterns, etc etc
I started off with a £75 borrowed guitar for a year, this was fine until about a couple of months ago, where i bought a Ibanex Gio £200 guitar, this is brilliant, and will last me a good couple of years, where i will buy the next stage up!
Those 3 guitars i have seen are intermediate guitars, if you are at this level i would get the SG copy, personally
Les Paul - Wide neck, maybe uncomfortable (suggest trying it out)
Dean V - Don't have brilliant pickups, and personally looks a bit meh
SG copy - Best bet out of the 3, looks good, sounds nice, and supposidly plays good to
Remember, buy a decent amp aswell, if you want pleasant sound by a line 6 spider 2/3 amp, these are beautiful but cost the most!
Well pm me if you want to chat etc, this is just my view!
