Wedding planning software

Is anyone using wedding planning software?

Does it contain a section for seating arrangements that can be printed out?
Does it take into consideration the layout of the reception (ie can you input the dimensions of the room and where the tables are)?

I really think I need something like this. The cheapest I found was $36.95. Is that reasonable?

If anyone has one, please let me know where you got it, price and if you like it or not.

Thanks!!!!

I got a book from Barnes and Noble called easy wedding planner and it came with free software.

It has budgets, addres info, but I am not sure if it has seating charts. I havent used my software yet
