My Tusa TR-200's have served me and then my kids well through the years but parts are now a thing of the past and need to be replaced. Trying to decide between the RS-460 (Tusa trade in program) and the Oceanic CDX5/Alpha8 (another trade in program). Reading/searching they both seem to be solid regs so I was wondering if anyone has used both and can give a comparison. Also real world experience with depth, warm/cold, service for if I need it away from my local LDS, etc. Mostly will be used for strictly recreational warm water diving but thinking about taking my son with me to Bikini. If either would work fine there it would be a bonus but not critical (my own current set is a Mk 18 with G250's). I need to buy another set anyway and can spend more on it later. Currently gearing up for another 10 days in Cozumel come 4/3 and trying to get my stuff gathered up and ready.
