I'd suggest going up to maybe a 7 or 8 wt 10-footer if one wants to get past 60 or 70 ft. I have one of each in Sage blanks that I use for steelhead. A weight forward line and learn to double haul. With good technique one can do those casts with a 6 wt, but things get tougher if one has to fight winds.
If one wants a bit more quality on a budget and is somewhat handy, he might buy a ready to wind kit at about 2/3rds down to maybe 1/2 the price of an assembled rod. I have Sage, Orvis, Meiser, Loomis, and Cabelas rods that I built but could not afford as assembled units. From 6 ft 2 wts up to 16 ft 10 wt Spey rods. Some fly shops sponsor build classes, and with some of their equipment like rod turners and a few pointers, one can do a top-notch custom job.
If one really wants to reach out (like 200 ft), a transition to a two-handed "Switch" rod might be in order. Here's a link to one of the high-end makers. One could take a look at his blanks and kits and something there might float your boat. These are actually shorter Spey rods with a different casting technique, but they will really blast out the line over medium to large water. A couple casting lessons would be in order as it's a bit difficult for us aged single handers to master. Not something that one would cast to shy beaver pond trout, but capable of handling steelhead and salmon.
Meiser linkA more budget minded linkJust an example in the above link. I don't have a dog in the fight, as several other brands/makers offer similar models.
Good luck and tight lines,
