NTSC Atari 2600 on Europe = Success?

Hi,

I recently acquired a PAL 6 switch Woody along with a Harmony Cart.
But I'm finding out that PAL games are not as playable as NTSC ones (20% slower). And there are a lot of games that are available only on NTSC.
Also on my TV (Sony KDL40W2000) NTSC games can't get a stable picture so they are unplayable.
So i'm considering selling this console and buying an american NTSC instead.
But i have my doubts that it will work on a European TV without  composite modding the console.
Any of you had any success making it work in Europe without modding the console?
If so what tv brand/model are you using?

Thanks,
Pedro
