It's a long way but you could always try and get to one of the other games in the UK (The Humans vs Zombies UK facebook group keeps a directory). Otherwise, just try asking- a load of people at my school didn't seem like the type of people who'd play, now some of them are coming to the High Wycombe game when it starts and one or two have come with us to a Winchester game.
Edit: Looking through the directory, the nearest game to York would be Leicester. Not ideal, and they play irregularly at best.
With regards to the Longshot, as an owner, I can say that they are fun to use due to the bolt-action style priming handle and front gun. However they are quite expensive and in terms of range they don't out-perform even the Nite Finder, which is the cheapest readily available blaster in the UK. It's definitely not a good one to start on.

This is only after their owners replaced springs and internal parts, even rebarreling them. No Nerf gun shoots like that out of the box. In any case, range isn't really a concern for HvZ- you tend to come across zombie "Ambushes" rather than long range firefights. And since they have to charge at you to tag you, something that can unload a lot of darts quickly will have a better chance of hitting them than one insanely powerful dart.
