Plenty of very reliable options for not much money (and frequently, more expensive does not equal more reliable). Most things start to go wrong when people tinker with them (albeit, that is part of the fun to be fair). If you haven’t actually played yet, go along to a couple of days and rent the kit so you can see if you like it. But once you do, you can get some good solid guns for less than £200 that should last a good while. Obviously, nothing is perfect, and you might get unlucky. but the good news is that parts are cheap, and - with youtube as your guide - fixes are usually easy.
