Chico,
It just seems to me that there must be other reasons besides cost that are keeping these primarily rec-based clubs away from SCYSA. The annual registration fees of $8 for U6-U8 and $10 for U9 and above do not seem horribly out of line with the non-SCYSA-affiliated organizations. The other SCYSA costs you mentioned are for Select teams.
The bureacracy and paperwork required could very well be an issue. Philosopical differences may be another. Any other reasons why these clubs avoid SCYSA? The costs for recreation alone just do not seem that much different to be the primary reason.
If anyone is interested in checking out the specific SCYSA fees, their Registrar Fee Sheet is availble on their web site at
