About those guns....
Depends what you intend to play really.
If you want to go to lots of woods sites and general group days then you don't need to go spending the earth.
You might want to spend a little more if you even think you might want to play in tourneys in the future (or back in the future).
If you're not sure (join the club) then pick something that isn't too cheap, so ignore the basic spyders etc. Look at markers for around the 200-250 mark so in your range would then be the cheaper end electros (dragun, spyder flash). What you could also do is pick up a 2nd hand marker (my personal choice) they lose very little value, you can get some great deals from shops and the classifieds here on P8 plus you can acquire some lovely markers, see your original idea of cockers shockers and automags.
If you have no kit what-so-ever then I recommend trying to find an all-in-one deal that'll solve most of your problems by suppling you with a marker, air/CO2 system and any needed expansions etc for one buy. Goggles are a bonus but you can have fun trying them in stores anyway
Anyway that's my 2p worth.
If you are mega enthused, spend the money, if not, get yourself a nice 2nd hand marker from someone or someplace that you can trust.
