well, what shows are you planning on seeing? if you're planning on seeing shows that're consistently selling out (I believe someone posted a list in your TKTS thread, but it's usually shows like Wicked, Jersey Boys, Billy Elliot and now West Side Story), I would buy them in advance. you don't need to jump on tickets right now, but definitely in advance.
for anything else, Playbill has all the rush and lotto information on their website, and the TDF site has a list of shows that were on the TKTS board the previous week. I'd keep an eye on that, to gauge what you're chances of scoring a discounted ticket are

When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
