Well - for cigars - I would only do one or two types - a natural (light shade wrapper) and a maduro...
I would tend to shy away from the 'samplers' where you get one of each type - they tend to arrive dry and in poor shape... (all the singles left from boxes...)
Remember - after they arrive keep the boxes sealed - or they will need to be kept protected and at ~70°/70% humidity till your event...

I don't know your budget or how many folks are invited - but here is a good starting point:
Siglo: http://www.mikescigars.com/cigars/si...e-iv/box-of-25 (this is a great price)
Partagas: http://www.mikescigars.com/cigars/pa...ales/box-of-25
Romeo-y-Julieta: http://www.mikescigars.com/cigars/ro...o.-4/box-of-27
All great smokes...
I always buy from Mike's Cigars of Miami
Been a customer of theirs for 20+ years and never a problem.

The Macallen 18 is a great scotch....
