I know that automatic brewers are heresy here, but this Iced Tea Maker works great with loose leaf tea. The pitcher it comes with is kind of meh but you can use any similiar-sized pitcher. It goes on on sale sometimes for $29
I even use it to brew hot tea directly into a 32oz thermos sometimes when I am in a hurry in the morning.
I had the square version of this (tm 75)? It leaked all over the place. This one appears to also. https://www.mrcoffee.com/iced-drinks-summer-sale/TM70.html
They have another one (used to be distributed by Oster) that's 2.5 quarts with a glass carafe. I like it. Hasn't leaked yet. I got mine on close out (bought 2!) but they're pricey.
I think MR. Coffee took over the line. http://www.amazon.com/gp/product/B00CEILY9W/ref=pd_lpo_sbs_dp_ss_1?pf_rd_p=1535523722&pf_rd_s=lpo-top-stripe-1&pf_rd_t=201&pf_rd_i=B0049N6JZE&pf_rd_m=ATVPDKIKX0DER&pf_rd_r=0MQHVM7N8SDK9JG8MSYD
