Recommendation for small nonprofit

Hi there! I am drowning in research trying to find the right CRM for my small nonprofit.

We have one full-time employee and a couple part timers. We have under 2,000 constituents at this time.

I'd like our new CRM to have the following capabilities without being overly cumbersome:

• Membership management (online sign ups, renewals, acknowledgements, etc)
• Donor management (online forms, acknowledgements, etc)
• Event management (online sales forms, acknowledgements, check in, etc)

What do you recommend? Thank you so much!
