Dolphin Entry Door Lock Replacement

My entry door lock is broken and has to be replaced. Has anybody else had to do the same recently and can you tell me what model door lock and brand you have used? I think that my old lock was the Trimark T-507, but it is not marked anywhere with a part number. I did talk to the Trimark folks and they tell me that there is a newer replacement, but they are quoting me $ 224 dollars. I have seen online other models that are less expensive, but I am not sure if they will fit my coach. I am looking for some one with the same coach as mine that might have recently gone thru this same experience and would be able to point me in the right direction.
Thanks in advance,

The cheaper ones may be for a trailer not motorhome. Because people ride inside it has to meet motorvehicle lock requirements.
