A lot of folks write off springers as a waste of time, however I find they are invaluable to introduce people to the sport at a very low cost. Not to mention, when you have a springer-only loadout you have to plan your tactics with your team very carefully because every shot has to count. My favorite spring loadout:

I have found the UHC MP5 SD3 rivals many sniper rifles at 2x or 3x the cost!
Non blow-back Co2 pistols are also very low cost and very high performance, these make great sidearms due to that fact.

The advantages:
- Co2 is more powerful & efficient
- very simple, low maintenance this is all you need aside keeping it clean http://www.pyramydair.com/cgi-bin/accessory.pl?accessory_id=222
- high reliability if properly maintained (my similar .177 models have had 10+ year lifespans) due to brain-dead simple mechanism.
- cheap magazines (see source link) low as $5 each
disadvantages:
- double-action only (no blowback, less realism)
- no hop-up
Electrics obviously have a great advantage, you can have full auto with no extra gas consumption or cost. This AEP is inexpensive, good quality and full auto!

On the down side, the small gearbox can only fit a somewhat weak spring and lower power (compared to an AEG or Co2) as a result.
Good quality AEG rifles can be had for $100+ for CYMA AK and JG brands. My Echo1 G36C is is a great choice for either CQB or woodsland play and highly reliable. Weather you need one or not depends on what the opposition has :) This one is just under $100 and is good quality and very reliable

The JG brand is also great "bang per buck" similar to above:
