the cheapest but best disc lock is a simple good quality padlock(with a pin that will go thru disc hole!) i attach a disc reminder to mine that simply goes from disc to bars to stop you forgetting to unlock before you ride off! as already said te bike could still be lifted into van or similar! a good u lock or good chain and padlock is better (or as well as) and you can get them that will fit under seat or come with a mounting bracket to fit on bike ,try to attach the bike to something if possible
