Assigning software/platform

[Paintguru]

I'm taking over umpire assigning duties for our youth rec baseball league, and I'm looking to assigning software/platforms for the spring. We have about 50-70 umpires and probably 400-500 games for the year. Obviously we'd like to keep costs down, but still want basic features like ability tracking, multiple assignors, etc. As an official, the assignors I've worked for have used Arbiter and GameOfficials, but again, those seem a bit pricey. I'm looking at assignr.com and horizonwebref.com, which are web based platforms that seem to have a nice balance of features and price. Anyone use these or have any other suggestions that I should look into?
