You'll find one somewhere. I usually buy second hand games from the internet (don't worry, I feel bad while doing it too), but maybe you have more reliable and accessible physical shopping mediums.
I remember running into the YouTube channel Super Bunnyhop a while back, and found his reviews and critical close-ups on Metal Gear games to be very true and eye-opening. Recently he did MGS3, and I've come to realise I may have been more than right. MGS3 isn't the best 3rd entry into a videogame series. No it isn't even the best 3rd entry into any series. It's the best thing in the entire world. Better than any movie, book, game or piece of extremely comfortable furniture any old day!
EDIT: If you're going to play Metal Gear, try approach it with an open mind.
Instead of worrying about the poor resolution in MGS1, admire the minimap.
Instead of hating on Raiden in MGS2, admire the minimap.
Instead of frantically worrying about the lack on minimap in MGS3, use your natural senses like a normal human being.
Seriously, I was so caught out on MGS3's lack of minimap at first I resorted to using the tranq. gun all the way trough… but then learnt there was more to life than that. Like using the sniper rifle, and knifing things. Like seriously, all I need in that rifle, and my knife and I'm set!
EDIT2: If you are buying the Legacy Collection second hand though, I advice you make sure it includes the download vouchers for the comics and MGS1. You can't start without MGS1!
