cheap trellis and tulip trees???

2 questions: first of all, i am in the pacific northwest, in eugene, zone 8b, i believe. i'm planning on planting morning glory seeds in my front garden, but i would like to find a trellis. anyone have any ideas as to where to find trellis for cheap? (i've had my eye peeled for people throwing some away, but so far no luck, so i'm considering purchasing some.) how long will it take for the plants (starting from seeds) to grow tall enough to vine and actually need the trellis? and finally, there are the most amazing, gorgeous trees opening around here... i thought they were redbuds, but the branches don't seem to have any leaves, only the most incredible, tulip-like blossoms. i'm in love and i must know what they are! i've never seen anything like them!
