We use the Laps-Free program with I-LAP counter,and so far it works great.Its more basic than the other programs. But if you are trying to keep the price down( its a free program),the Laps-Free will work just fine,and has great support.We had a question on a Sunday and had the answer back in less than 2 hours from first email.
Alycat is the least expensive "full" featured program and works well.The rest of the program Jlap and RCpro are expensive for what you get .Alycat is close to those for about$260 or so compared to over $500+ for the others. JLap does offer the online result option,which you pay for.
The one thing they ALL have in common limited instruction for the first time user.
I do not no much about Slyfox and BBK,sorry.
