Hi Guys. I have tried to find out the working solution for implementing simple events booking system in Drupal 6 (limited places, payment, signing up/buying few places for firends). System does not have to be big but easy to customize events to reserve/book places for.

I was surprised of not finding much complete solutions. Most of the time I was directed to use modules like: Date, Calendar, Singup, Singup Ubercraft integration, Ubercraft.

Does anybody of you has tested it? Is it working and customizable or you would suggest other alternatives on the subject?

Wiil appreciate any recomendations.
