I would greatly imagine there's a massive throughput of kids... My local place is 45 for the day... That's not a tiny amount for a kid... And to get your own rifle?... You need adult money, I think... To get yourself a nice setup may cost you £500 notes... Plus range fees and ammo.
It's an expensive hobby...
It cost more than £45 for paint balling,My son was costing close to £70 for the day (When you add ammo,lunch,travel cost etc)
I can take me & my son out doing airsoft for £50, that covers both of us for the day & you get lunch included. At one point my son was doing Tae-Kwon-Do which was £50 a month (Not including pads, uniform & belts). I knew one dad who's son was doing that & BJJ which was another £60 on top of that (So he was paying £110 a month & he had two sons).
I know for a fact parents would pay £45 for the day no worries at all.
Coming back to airsoft for a moment My son's loadout, with an Ares M4 cost less than £200. I think that's a bargain, considering I'm a recent convert from mountain biking where my gear system cost me £450 & my wheels cost close to £900.....my bike frame is worth over £1000, then you have kit to wear etc.....on mountain biking over the space of 3 years I spent over £4000 (and I could still be adding to it now if I have not realised what I was doing), also adding travel cost's to go to bike centres all over the country (Wales, Scotland etc)......So I really don't see airsoft as expensive.
I think you'd be surprised, If I had the know how & a business brain I'd definitely consider setting something up on a Saturday afternoon.
