Magnetic Tankbags?

I am tired of taking a back pack with me to hold my hat, wallet, keys, phone, etc.  I have been "shopping" for a quality magnetic tankbag that has style and have only found a few.  My question is does anyone own one and if so how do you like it?  I am partial to a joerocket bag I found.  Heres a link to bag info.

Good bag?  Any info. is appreciated.  

Hawk,

These are the two best tank bags around, I have both.

They both convert to packs, I never use that though. The big one used to come with a Platapus (sp) hydration system. Both use high quality materials and both are well made. The little one has water resistant zippers. The map pocket on the larger one is funny. They used to only be available direct, but they may be released by now.

Thanks for the info.  

I bought the JR Manta Bag for my girlfriend. After hundreds of miles of riding, we can honestly say that it's simply excellent. Even riding in very, very high cross winds to and from Willow Springs (through the dessert, crazy wind), it didn't even budge. Very impressed.

I got if from KneeDraggers for about $35; everyone has it for $35 now, except for Dennis Kirk (I don't like them anyhow).

For me, I recently picked up the Coretech super-mini tank bag and have had it for a few months now. Just as impressed with this one as the Manta bag. We just got back from a 130+ mile ride today and it never moved from where I put it. Doubtlessly worth my fifty bucks.

Mind you that these are both small tank bags, but that's what we wanted. Enough for a day's ride. Perfect for our needs. Hat, keys, wallet, extra shirt, etc...all fit great. The super mini even has little pockets for pens and paper & such.
