Modding Atari hardware- All in one source

[seastalker]

I have Atari 8 bit upgrades of U1MB, Antonia, UAV, Sophia... they go to my fave systems. Now, I got a light sixer 2600 and got wondering about mods and started a thread for the 'B systems' of our collections. For example, I LIKE the 2600 but having a CRT VGA monitor and a MIST keeps me happy when I revisit the 2600. I just got a light sixer but don't feel I need to upgrade beyond a simple composite mod unless a S-Video mod was easier or cost the same.

 

Firstly, what mods would people suggest for my light sixer? As I already have a MIST, RF on an old set is nearly fine enough for nostalgia. I'm up maybe for inexpensive mods and keep my Sophia for th ones I play more often.

 

Which systems would you NOT or MINIMALLY alter and why?
