I use the canare and have never had an issue. Will go 300' @ 1080p but if you step down to 1080i or 720p I've gotten almost 500' through 2 pieces and a barrel.
If you don't already have the tools to terminate you may want to find someone close by that has them. The tool set to make them runs $200-$300. Nice to have though since I've rebuilt my camera rack with all custom looms and it came out great
