Like the tourney scene, scenario hosts naturally work hard to make the game rules are fair and enforced, everything runs smoothly, and it's fun for everyone, but you're aways going to have problems. That in mind, DDay is worth checking out.
Decent radios are a great asset if you're playing with team mates you work well with. Look into the Puxing 777 series. They run about $60 and are way more secure and have a much better range than the Walmart radios. With everybody using those and channel surfing on those, com security is imposible and general use is spotty at best. It gets worse than a theme park (where most people have given up on the idea years ago anyway). DDay uses the VHF version for allies and UHF for Axis if you want to take that into consideration.
