Don't sell yourself short. Even if your stuck in a full maintenance contract Mods are pretty much always paid for so this is your opportunity to get what you WANT to work on for the next 30 years. Yall are gonna make money either way so pick what's going to be best to service. There's a reason TK stuff is always modded to better equipment but not the other way around. I wouldn't want to work on an ld-03 with an interface board when it could've just been a GAL operator.
