[TokyoSeven]

Hit up a local game and browse the kits, see whats out there. Most players or kind enough to fill you in on details of their set up. Any AEG can be refitted or modified to accept a larger battery. If you are looking for a dependable brand, that would have to be Tokyo Mauri. Good quality, good QC, effort put into R&D, a modest FPS out of the box (A consistent 280fps in most cases depending on model) and as long as you take good care of it with routine maintenance it should last you years. Or atleast thats what my opinion is. However if you want the most bang for your dollar and what something a little more powerful out of the box then a JG or Jing Gong brand airsoft gun is what you want. JG simply put takes TM designs or other manufacturers designs and remakes the guns in their own company using slightly less quality parts but none the less they are a reputable company and churn out a modest quality airsoft gun with a very decent fps fresh out of the box in most cases. (350ish fps maybe 350+)
