+1 Markos! The Brittney/Jewell was outstanding! Jewell is soo cute and loves what she is doing and got one of the best reactions out of Britt then anybody has(master excluded of course).
I, like Papi, have supported them from the very start and they are at the top of my list of producers with TIB and Jeff. Every once and a while, one is not as great as the rest, but you know what, sometimes my favorite TV show has a episode or two like that also. But the good news is that the great overwhelmingly outweigh the "ok". I'd recommend them everytime.
I'm also a big fan of previews and they sell me a ton of material especially from TIB, but the guys I mentioned keep me a loyal customer by their history of great material more then the preview. TickleCentral has stop putting up new previews, but you can see a ton of their previews
here. Themselves, TIB, and Marcusb all have a lot of previews on their own sites, so sometimes you just have to peek around.
As for the prices being the most expensive, I think Clips4Sale make you charge a certain price by the minute(a lot people charge $1 per minute). So when someone charges less, you are getting a pretty good deal. But they can only charge so much under a dollar for a minute(producers correct me if I'm wrong). So when it looks like Tickle Central is charging more then anybody else, look at the running time of the clip. Quite often you are getting more minutes then everybody else, with the Tickle Master series sometimes going almost 20 minutes. Great value for the time.
So as Papi said, don't give up man, the good stuff is out there
