I think this war between oleg and stuffy is kind of useless, you each have your own points which are both true. I myself would never use an E-amp series amp, I am a non-depoer which is why I want to be the most eco possible, even if it requires an investment. If you look at the yearly market history of the A103 amp, hover your mouse where it peaks up, you'll see one sold for +170.23. Thats me buying my first amp
, and now its down to +70 or so nowadays, I "lost" 100 ped from the investment, but the amp has saved me much more than that since I've unlocked serendipity a while ago, and as Gluepot stated, it takes THOUSANDS of peds to get there so I'm sure I got all my peds back, and then some.
I'll step out here and analize it from a 3rd person point of view so that even if I use A10X amps and dislike the E-Amps, I'll state the pros and cons of either.
A10X
Pros: -Makes the weapon you're using more eco, saving you ped over a period of time.
Cons: -You need to spend 100 ped to buy the amp and therefore have less ped to hunt with. (which is no problem btw if you have another 200 or so ped, aslong as you manage to break even, then you just recycle these peds over and over)
E-Amp
Pros: -Cheap way of making your weapon more powerfull without having to spend much initial peds into the investment
Cons: -The economy is not altered in any way, which is ok, but I'd rather save ped than not save ped
Looking at it this way, if you just play EU a couple hours a week, and dont want to bother investing in an A10X amp then the E-Amps are perfect, they'll let ya get that boost of damage you might need and not bother about saving a few cents.
But if you play EU a couple hours a day, or maybe more, then you might start thinking about hassling together an extra hundred ped to improve the economy of your hunting, only then would it be worth it.
Hope this helps
