want to build a directory similar to yellow pages... should i wait?

[isntworkdull]

Hi all

completely new to all this, i have a online shop but i want to make a directory that will advertise customers who install my products (and similar products).

so i would want a set up like yellow pages, and i came across this site while looking into directories.

basically while reading your forum i see you are releasing a new script next month which is apply called yellow pages...

so i wanted to know should i buy your script now, and upgrade to the yellow pages when it comes out?

or would it be better to just wait and buy the yellow pages version?

please advise

thanks
James
