Welcome, I was in the same place as you just a few weeks ago. I bought a cheapey bike from Sports Authority that was on clearance. It's a no frills cruiser no gears, and a coaster brake. I just finished the engine install and have been riding it the last few days. I plan on adding caliper brakes at a later time.
You can see my build thread here:
BTW: thanks for asking the HT question because I had no idea what it was either.
