Guess I'm being overly paranoid

I'm currently a top bidder on a XA on eBay. The owner said that the seals (?) have been replaced... I'm hoping he did a good job on it :X . He's Aussie and if I win, I'll be paying a pretty penny for it (close the $70 USD)!

I'm planning on picking up another and possibly a third for my trip. It'd be nice to have 3 different types of film (ISO 100, 400 (for flash), and 800 for indoors)

Thanks for your help Keith!
