I have a Kraken and Chi-raken(?), and both eventually leak when placed on their side for long periods of time (over an hour). Had to change my bedsheets once after half a
tank leaked onto them
Its low capacity aside, I'd highly recommend the AGA T-3 for a cheap, reliable and leak-proof Genesis experience. Well, leak-proof from the tank at least. The shape of the top cap tends to encourage a lot of condensation build up, and it's a good idea to be extra careful when pulling it off to refill, etc.
