Opinions on Gottliebs Sys3 compared to Williams Sys11

Hi !
I'm an absolute beginner - who got my first pinball, Big Guns (Williams), quite recently.

Well- I am totally hooked on pins now and I'm already looking for the second machine.

Even though I am an absolute amateur on fixing electronics, I'm about to buy a proper electric tester and soldering station to be prepared when the machines start to show problems. However , of course, I´m the kind of guy who prefers when things function and don´t need repeated repair work. Or at least that those repair works don´t turn out to be too challenging.

In that respect - and taking into consideration that I'm a newbie : is there anything that should be given special consideration if my next buy were to be a Gottlieb Sys 3 ?

I've had people warn me from getting a Gottlieb Sys 80- because they are said to be very hard to troubleshoot and work on. Does that apply to the Sys 3 Gottliebs also ?

So far I've had my sights set on getting one of the following titles: Surf N Safari, Super Marios Bros or Lights, Camera, Action.

Thanks in advance for Your thoughts.

Thanks a bundle for the information. I will definitively put those aformentioned Sys3-titles on my hunting list.

Thanks Amkoepfer ! I must say - I really am reconsidering the Sys-3-games - from having placed them in the "less-of-a-game"-league up until now. I will try to test a few of them before buying, but from what I've seen on Youtube there seem to be quite a few exciting titels in the Sys3-line. One little, and maybe funny, detail that I like is those blue-looking Futaba (?) displays on some of them.

Haha- thanks, I'll keep that audio-warning for Wipeout in mind

Huge thanks to the contributors of information and hints in this thread. It's really appreciated.
Now I'm just watching the market and wait for the right Sys 3/GLB-opportunity
