What is the best Extended Battery Back Cover

[BillJr106]

I bought one with a cheap-o battery because it was more uniform in shape than the Seidio. However it seems to want to come off rather easily... jsut wondering if there are nay good build quality covers out there...

I have the Seidio 3500 and love it but I have to admit that the battery cover is getting a little sloppy in the mid-section. Of course, I have had to pull the cover many times will rooting, etc. and gave it a pretty good work-out. If anything, it was much tighter than the stock, which may have accounted for the trouble.
