I have not used a photographer for a communion party. However, for the last three bridal parties I've been in, the couples have all used Silverfox and been quite happy--if that helps at all.
I use Teresa Geraghty Photography for our Christmas pictures every year. She does beautiful work She does Communions too-she actually just posted a beautiful session on her Facebook page. Not sure what she charges for that but if you message her on Facebook she is very responsive.
