newbie buying used DCS

Handhelds are the same. I wouldn't hesitate to buy any version    except... an early G from around 02  (nothing to indicate version on the bottom) and a I3a . 2008?.  Everything else can be upgraded software wise.

Having said that  we still a early G on our large super mode layout with version 5 software.

How do you know the condition of the stuff you're thinking of getting is the question..

I suppose if you can purchase it cheap enough  it may be an option . I think I'd go new unless I knew the person.

I wouldn't buy anything other than the latest TIU (Rev. L) and remote from, an authorized MTH dealer for the following reasons:

• The Rev. L TIU has newer technology and improved performance over any previous model TIU.
• The Rev. L has a USB port which negates the need to purchase a separate USB to serial cable.
• The price difference between a new Rev. L and a used Rev. L is at most $40-50, and a new Rev. L, purchased from an authorized MTH dealer, comes with a 1-year MTH warranty.
• A used TIU comes with whatever issues the previous owner fails to mention, often because the owner isn't DCS-savvy enough to recognize that there is an issue.

While all DCS Remotes are pretty much the same, thumbwheels have been known to wear out . I'd the remote purchase new from an authorized MTH dealer for some of the same reasons I've stated above regarding the TIU.

Personally, I would follow Barry's advice above and purchase a new DCS system (with Rev L TIU) from an MTH dealer.

I am on board with a new R-L also.  If you do go the other way, try to snag one from a forum member.  Stay clear of other sites.
