Yes Deep Search has a few but its all down to How much you want to pay . As far as Singapore goes just take a trip over to Loyang offshore base.
To find out which yards you want to check just go to Google or Yahoo and type in Rov Company’s Singapore . As you entry Loyang many of the yards are down side roads left and right leading off the main road .
Ok here is a map of the base you can see you drive into the base from Loyang Crescent , I did it in 2 days " North Side Roads " Then South down the SOPS Ave side .
Best hire a taxi and drive around the area till you find some thing interesting as its to hot to walk around . The gear it wont look pretty but it should be cheap but it will need a total rebuild in the past I have found old 225 LARs and TMS plus a old UFO TMS and LARs
Best of luck with your search .
