Does anyone here have a completely bug-free Fiverr script? Will Pay...

Am thinking of buying the script off someone on tenbux.com as they apparently say their script is bug free, but I thought I'd ask around on here as well. I'm not sure what a reasonable price is to pay for a "free" fiverr script on here but if USD$15 is a reasonable price I will take it. I have downloaded a "free" Hiverr script and have tried fixing a few bugs on there but there are too many for me to deal with, and with uni etc I don't really have the time to sit down and fix all their bugs, so hence I am looking for a "free" script that is COMPLETELY bug-free and operational (I have a portable server I can test the scripts on). If anyone can help me out it would be very much appreciated, I will even give you lifetime featured gigs on my new site if this goes well .

Thanks in advance!!

P.S If you want to see the bugs etc on the script I have on my hosting account you can visit or if thats not working (the domain is most likely still being propagated etc - should be all good within a few hours), . Apparently my hosting provider does have Zend Optimiser enabled.

I just deleted all the files off my host so theres no point in trying to visit the site, figure until I do get a decent bug-free script as described I might as well test some other things instead...
